Hermoupolis Town Hall: The landmark at the heart of Syros

On Miaouli Square, in the heart of Hermoupolis, stands one of the most recognisable buildings in Syros. The Town Hall is more than the seat of the local municipality. It is one of Ernst Ziller’s most important works and a building closely connected to the period when Hermoupolis developed into one of the leading urban centres of modern Greece.

Even if you only have a few hours in the city, you will almost certainly pass by it. But it is worth stopping for a little longer to discover the story behind its impressive façade.

The history of the Town Hall follows the remarkable rise of Hermoupolis itself.

The city emerged during the years of the Greek War of Independence and, within just a few decades, developed into an important centre of trade, shipping and industry. Its port played a leading role in Greek commerce, while public buildings, theatres, mansions and grand squares began to shape the city around it.

It was during this period of prosperity that the decision was made to build a Town Hall worthy of the new city.

There is another reason why its history feels particularly relevant today. In 2026, Hermoupolis celebrates 200 years since it was officially named in 1826, giving a visit to its historic centre an added significance this year.

The Town Hall was designed by Ernst Ziller, one of the architects who had the greatest influence on the appearance of Greek cities during the 19th century.

Construction began in 1876 and continued for many years. The scale of the project is still immediately apparent today. The building occupies the entire upper side of Miaouli Square, while the broad staircase leading to its entrance makes the façade appear even more imposing.

It is also worth viewing the building from the opposite side of the square. From there, you get a much better sense of the symmetry of the façade, its arches, balconies and architectural details that are easy to miss when standing directly in front of it.

Despite its historical and architectural importance, the Town Hall has not been turned into a museum. It remains a working public building and is home to services of the Municipality of Syros-Hermoupolis.

Inside, however, you will also find the Archaeological Museum of Syros, something many visitors to the city are unaware of.

The museum has occupied four rooms of the Town Hall since 1899 and is one of the oldest archaeological museums in Greece. Its collection includes finds from Syros and other parts of the Cyclades, offering a glimpse into the island’s history long before Hermoupolis was founded.

If you have a little more time, a walk through Miaouli Square can easily be combined with a visit to the museum.

As part of the celebrations marking 200 years of Hermoupolis, the Town Hall is hosting the “Inside Ziller’s Mind” exhibition in 2026, dedicated to the architect and the design of the building itself.

The exhibition offers a different perspective on the Town Hall, exploring the history and process behind its creation. If you are in Syros while it is running, it is a good opportunity to learn more about the building and its architecture. Check the opening days and hours before visiting, as this is a temporary exhibition.

The Town Hall’s central location makes it easy to combine your visit with a longer walk through the historic centre of Hermoupolis.

After spending some time in Miaouli Square, you can continue towards the Apollon Theater, then walk on to Saint Nicholas Church and Vaporia. Head in the opposite direction and within a few minutes you will reach the market, Chiou Street and the waterfront.

There is no need for much planning. Distances are short, and this part of Hermoupolis is best explored on foot.

Miaouli Square is only a few minutes’ walk from the port and the waterfront. If you are staying in central Hermoupolis, you will not need a car to get there.

If you are arriving from another part of Syros, it is usually easier to leave your car at one of the parking areas around the centre and continue on foot. Our guide to parking in Hermoupolis covers the main options and some useful information before you set off.

The Town Hall is impressive in its own right, but what makes it truly interesting is the history behind it.

Hermoupolis did not follow the same path as most settlements in the Cyclades. It emerged and developed remarkably quickly during the 19th century, acquiring a distinctly urban character that is still visible today.

The Town Hall and Miaouli Square are a good place to start, not only for a walk through Hermoupolis, but also for understanding the history that shaped the city.
