Zadar History Walking Tour: Roman Forum and St Donatus

Walking through two thousand years on one peninsula

Zadar’s Old Town sits on a narrow peninsula, and almost everything worth seeing on foot is packed into a walkable loop that never strays far from the water. What makes the city unusual is how visibly its layers overlap: a Roman-era public square sits directly beside a 9th-century round church, which stands a few minutes’ walk from a Romanesque cathedral, all inside walls that were themselves rebuilt by the Venetians centuries later. This guide follows that layering in order — Roman, early medieval, Romanesque, then Venetian — so the history reads the way the stones actually sit on the ground, rather than jumping around the map.

You do not need a guide to follow this route, though several Zadar walking tours exist precisely for this stretch of the Old Town if you would rather have the context narrated as you go. Either way, the route below works as a self-guided itinerary, and it pairs well with the separate Zadar Old Town walking tour if you want to extend the day toward the Riva and the Sea Organ.

Start at the Roman Forum

The Forum is the natural starting point for a history-focused walk, and it is also the site’s centrepiece: it is generally described as the largest Roman forum on the eastern coast of the Adriatic. Zadar, known in the Roman period as Iader, was an established Roman colony, and the Forum served as its civic and religious heart — the open square where public life happened.

What survives today is an open-air site rather than a reconstructed building: paving stones, column bases, and fragments of masonry lie across a broad rectangular space, with some columns still standing. One granite column near the site is popularly known as the “Pillar of Shame,” reportedly used in the medieval period to tie up and publicly punish wrongdoers — a detail worth pointing out as you pass, since it is easy to walk by without noticing it is anything more than a leftover Roman column.

Because the Forum is an open site rather than a ticketed monument, you can walk its full perimeter freely and take in the scale of it before moving to the building that borders it. No founding date more precise than “Roman-era” should be assumed for the Forum — sources describe its era and scale, not a single founding year, so treat it as a Roman-period civic space rather than reaching for an exact date.

St Donatus: a 9th-century church built from Roman stone

Standing right at the edge of the Forum, and impossible to miss once you’re there, is St Donatus Church — a round, pre-Romanesque building dating to the 9th century. Its shape alone sets it apart from almost everything else in the Old Town: a cylindrical drum topped with a dome, built in a style more common to early Byzantine and Carolingian-era churches than to the Romanesque and Gothic buildings that came later in Dalmatia.

Look closely at the base of the walls and you’ll notice something telling: sections of the church incorporate spolia — reused stone fragments — taken directly from the Roman Forum it sits beside. It is a literal case of one era being built out of the physical remains of the one before it, and it is one of the clearest visual links on this walk between Roman Zadar and early medieval Zadar.

St Donatus has not functioned as a place of worship for a very long time; it is deconsecrated today. Its second life is as a concert venue — the church’s stone interior and domed shape give it acoustics that musicians and organizers have leaned into for decades, most visibly through the summer “Musical Evenings in St Donatus” concert series.

If your visit coincides with a concert, sitting inside a 9th-century church for a live performance is a genuinely different way to experience the building than a daytime walk-through. Outside of performances, the interior is generally open to visitors, with Roman-era fragments from the Forum displayed inside — though exact hours and any entry fee shift by season, so check the current listing rather than assuming a fixed price or schedule.

If you want the fuller architectural and historical background on the church specifically, the companion piece on Roman Zadar and St Donatus goes deeper into its construction and later use as a concert space.

The Cathedral of St Anastasia and its bell tower

A short walk from the Forum and St Donatus brings you to the Cathedral of St Anastasia, Zadar’s main cathedral and a different kind of building altogether: a Romanesque church, larger and more conventionally basilica-shaped than the round St Donatus, with an imposing bell tower rising beside it.

The bell tower is one of the better reasons to build extra time into this walk — it is generally open for visitors to climb, and the view from the top takes in the Old Town’s rooftops, the surrounding walls, and the sea beyond the peninsula in more than one direction. As with St Donatus, specific opening hours and ticket prices for the tower climb vary by season, so treat any number you see elsewhere as provisional and check the current listing locally.

Together, St Donatus and the Cathedral of St Anastasia make a useful contrast to hold in mind as you walk between them: one round, early medieval, and deconsecrated; the other rectangular, Romanesque, and still an active cathedral. Seeing both within a few minutes’ walk of each other is part of what makes this particular stretch of Zadar’s Old Town denser with visible history than most cities its size.

Five Wells Square and the Land Gate

From the cathedral quarter, the route naturally continues toward Five Wells Square, a public square named for the row of five wells built into it, historically part of the city’s water storage system when Zadar’s defenses made an external water supply unreliable during sieges. It’s a quieter, more residential-feeling stop than the Forum or the cathedral, and a good place to pause.

From there, the walk ends logically at the Land Gate, a Renaissance-era gate dated to 1543 and one of the more monumental surviving entrances through Zadar’s old defensive walls. Those walls — along with St Nicholas Fortress in Šibenik — form part of a UNESCO World Heritage listing covering “Venetian Works of Defence between the 16th and 17th Centuries,” inscribed in 2017. The Land Gate is a clear physical marker of that later Venetian layer sitting on top of the Roman and early medieval one you’ve just walked through, and it makes a natural finishing point for a route built around the city’s chronology.

Suggested route at a glance

Stop	What it is	Era
Roman Forum	Largest Roman forum on the eastern Adriatic coast	Roman period
St Donatus Church	Round, deconsecrated church, now a concert venue	9th century
Cathedral of St Anastasia	Main cathedral, climbable bell tower	Romanesque
Five Wells Square	Public square with five historic wells	Later medieval
Land Gate	Renaissance gate through the Venetian walls	1543

The order above is the one described in this guide, but the sites sit close enough together that you can just as easily loop back or reorder stops depending on where you’re staying in the Old Town.

Doing it self-guided versus joining a tour

Walking this route on your own costs nothing beyond any individual entry fees at St Donatus or the cathedral bell tower, and it lets you set your own pace — useful if you want to linger at the Forum in the early morning light or catch a concert at St Donatus in the evening. The trade-off is context: a Roman forum without commentary is an impressive but somewhat mute field of stone, and the layered story of Roman-to-Venetian Zadar is easy to miss without someone pointing out the details, like the reused Forum stone in St Donatus’s walls.

If you’d rather have that context narrated, the Roman Tour Living History Walk is built specifically around this history, often with costumed or character-led storytelling that brings the Forum and its Roman-era context to life in a way a guidebook can’t. For something with a different tone that still threads through the same historic core, the Zadar from History to Fantasy walking tour covers the same Old Town ground with a broader storytelling angle that mixes documented history with local legend.

Either tour typically runs a couple of hours and covers the Forum, St Donatus and the surrounding streets on foot, which fits neatly into a single morning or afternoon alongside the rest of an Old Town visit.

Pairing this walk with the rest of your day

Because this route stays entirely within the compact Old Town, it’s easy to combine with other Zadar essentials on the same day. Many visitors do this history walk in the morning, when the Forum is quieter and the light is better for photos, then head to the Riva in the late afternoon for the Sea Organ and sunset — a very different kind of Zadar landmark, built in 2005 rather than the 9th century, but only a few minutes’ walk from where this route ends.

If you have more time and want to extend the historical thread beyond Zadar itself, the Venetian defensive walls that include the Land Gate connect thematically to Šibenik’s fortresses and St James’s Cathedral further down the coast — both covered in the Šibenik Old Town day trip and the dedicated St James’s Cathedral tour guide, both under the same 2017 UNESCO listing as Zadar’s own walls.

For an evening that shifts away from history entirely, the Night Swim with a Surprise Cocktail experience is a lighter way to close out a day that started at a two-thousand-year-old forum, and the private boat trip to Ugljan island is worth considering the next day if you want to balance the Old Town’s stone streets with some time on the water in the Zadar Archipelago.

If your stay covers more than a single day, see how many days to spend in Zadar for how a history-focused morning like this one fits into a longer itinerary, or check where to stay in Zadar if you want a base within easy walking distance of the Forum and Land Gate.

What this history walk is not

This is not a tour of Zadar’s beaches, boat trips or islands — for those, see the dedicated Zadar Archipelago and Kornati National Park boat tour guides instead. It’s also worth being precise about the buildings themselves: St Donatus is not the city’s cathedral — that is the Cathedral of St Anastasia, a separate and still-active building a short walk away — and St Donatus no longer holds religious services of any kind; its role today is as a historic monument and concert space, not a working church.

Historic Zadar walking tour FAQ

How old is the Roman Forum in Zadar?

The Forum dates to the Roman period, when Zadar (then Iader) was a Roman colony, and it is described as the largest Roman forum on the eastern coast of the Adriatic. No precise founding date is claimed here beyond that Roman-era origin.

Is St Donatus Church still used for religious services?

No. St Donatus is a 9th-century pre-Romanesque round church that has been deconsecrated and is no longer used for worship. Today it is best known as a venue for concerts, particularly during the summer Musical Evenings in St Donatus series, thanks to its distinctive acoustics.

Can you go inside St Donatus Church?

The church is generally open to visitors for a fee, and stone fragments from the Roman Forum are displayed inside and around it. Opening hours and ticket prices change by season, so check the current listing on-site or with a local tour rather than assuming a fixed schedule.

What is the difference between St Donatus Church and the Cathedral of St Anastasia?

St Donatus is the older, round, pre-Romanesque building next to the Forum, no longer consecrated. The Cathedral of St Anastasia is Zadar’s main Catholic cathedral, a separate Romanesque church a short walk away, with a bell tower that visitors can climb.

Can you climb the bell tower of the Cathedral of St Anastasia?

Yes, the cathedral’s bell tower is open to climb for panoramic views over the Old Town rooftops toward the sea. Exact hours and ticket details vary by season, so check the current listing before planning your visit around it.

How long does the Roman Forum and St Donatus walk take?

Walking between the Forum, St Donatus, the Cathedral of St Anastasia and nearby squares takes roughly one to two hours at an unhurried pace, longer if you join a guided walking tour or linger over each site.

Is the Roman Forum free to visit?

The open-air Forum area itself can be viewed and walked through without a ticket, though some structures and the interior of St Donatus may charge separate entry. Confirm current admission details locally rather than relying on a fixed price here.

Are there guided tours that cover this Roman and medieval route?

Yes, several Zadar walking tours are built specifically around this route, pairing costumed or historical storytelling with stops at the Forum, St Donatus and the cathedral quarter.
