Famous Landmarks in Zagreb
A hilltop medieval quarter of spires and a tower looks down on a Neoclassical lower town.
Zagreb's oldest landmarks sit together on the twin hill settlements now called the Upper Town: a parish church known for its patterned tiled roof, a fortified tower that once guarded a town gate, and a cathedral first raised in 1217. Stone construction, steep roofs and a defensive layout mark this medieval core, which predates the city's recognition as a free royal city in 1242. Downhill, on the flatter ground toward the Sava valley, nineteenth-century civic building added a different register: a Neoclassical theatre with a bright yellow façade, completed in 1895. The cathedral's present Neo-Gothic profile, with twin spires topping 108 metres, actually dates to a rebuild carried out after an 1880 earthquake rather than to its medieval origin.
Zagreb Cathedral

1217, rebuilt after 1880 · Hermann Bollé
Two matching Neo-Gothic spires rise side by side to just over 108 metres, visible from most of the surrounding city; the pale stone façade below them is dense with tracery, pinnacles and buttresses typical of a late-nineteenth-century Gothic Revival rebuild rather than a genuinely medieval one.
The original cathedral was completed in 1217 in Romanesque style but was heavily damaged during the Tatar invasion of 1242, after which it was rebuilt and expanded in Gothic style over the following centuries. A second disaster, the 1880 earthquake, destroyed large sections of the building. Architect Hermann Bollé led the restoration that followed, producing the Neo-Gothic structure seen today, including its paired spires. Dedicated to the Assumption of Mary and to two sainted kings, it was formally entered in Croatia's Register of Cultural Goods in 2013.
- It is described as the most monumental Gothic sacral building southeast of the Alps.
- The earthquake that forced its rebuild struck in 1880, more than six centuries after its first completion.
- It was only formally entered in Croatia's Register of Cultural Goods in 2013.

St. Mark's Church

1256
A steeply pitched, tiled roof laid out in a bold checkerboard-and-shield pattern showing two coats of arms side by side, above an otherwise plain stone Gothic-Romanesque façade and bell tower on a small square.
This parish church stands on a square in the historic Upper Town and ranks among the oldest architectural monuments in the area, with origins dating to the 13th century. It combines Gothic and Romanesque elements. The building is best known for its patterned tiled roof, which depicts the coats of arms of three historic regions alongside the city's own emblem. It remains a working parish church and is listed among Croatia's protected cultural goods.
- Its tiled roof depicts the coats of arms of three historic regions plus the city's own emblem, laid out side by side in tile.

Croatian National Theatre

1895 · Fellner & Helmer
A pale yellow Neoclassical building with a columned front and pediment, standing at the centre of an open square; the strong yellow of its façade is one of the more recognisable notes in the city's civic architecture.
This theatre and opera house is the oldest Croatian theatre institution, having officially opened on 24 November 1860, though the present building was completed in 1895. It stands at the centre of a central city square and stages opera, ballet and drama drawn from domestic and international repertoire, with more than twenty premieres and repeat titles performed each season. It is one of seven national theatres in Croatia and belongs to international networks including Opera Europa and the European Theatre Convention.
- The theatre institution itself is older than its current building: it opened in 1860, 35 years before this structure was finished.
- It is one of seven national theatres in the country.

Lotrscak Tower

1266
A compact fortified stone tower standing on the line of a former town wall, at the point where its southern gate once stood, overlooking the streets on the lower ground below.
This fortified tower stands in the old hilltop quarter and dates to the 13th century, when it was built to guard the southern gate in the town wall of Gradec. Its name derives from the Latin campana latrunculorum, or "thieves' bell," a reference to a bell hung in the tower in 1646 to mark the nightly closing of the gates below. It survives as one of the area's few remaining medieval defensive structures and is protected as a cultural good.
- Its name translates as "thieves' bell," after a bell hung in the tower in 1646 to signal the nightly closing of the town gates.

History
The city's earliest recorded core sits on two hills: Kaptol, referenced from 1094 and named in a document of 1134, and Gradec, granted status as a free royal city in 1242. Both produced the fortified, ecclesiastical architecture that still defines the Upper Town — the parish church of St. Mark, dated to the 13th century, and a fortified tower built the same century to guard Gradec's southern gate. The cathedral at Kaptol, completed in 1217, was badly damaged in the Tatar invasion of 1242 and rebuilt over following centuries in Gothic style. A second calamity, the 1880 earthquake, tore through it again; the Neo-Gothic reconstruction that followed, led by architect Hermann Bollé, gave the skyline its twin spires. Municipal life was formalised soon after, with the first mayor taking office in 1851, and expressed lower down the valley in Neoclassical civic building such as the theatre completed in 1895.
