Archaeological Museum of Syros
Founded as the central museum of the Cyclades, the museum is housed in the Town Hall designed by Ernst Ziller. Its highlights are finds from Kastri and Chalandriani, two of the most important prehistoric sites of the Cyclades, with sculptures, inscriptions and tombstones from the ancient city of Syros. Ticket EUR 5.
Miaouli Square and Town Hall
The marble-paved central square of Ermoupoli is the heart of the island's political, social and cultural life. It is dominated by the Town Hall, designed by Ernst Ziller, with its 15.5 m wide staircase, alongside the historic club that houses the cultural centre and the historical archives. A statue of Admiral Andreas Miaoulis of the War of Independence stands in the square, and a bandstand decorated with reliefs of Apollo and the Muses makes it the island's favourite meeting point, ringed by cafes.
Apollon Theater
Built in the 19th century to designs by the Italian architect Pietro Sampo, who was inspired by four Italian theatres including La Scala in Milan, the theatre first opened with an Italian troupe staging La Traviata. Restored after a long closure, it today hosts plays, opera, music and dance, and houses a small theatre museum.
Agios Nikolaos and Vaporia
In the prestigious Vaporia district, the Church of Agios Nikolaos, patron saint of Ermoupoli, was built in the mid-19th century to designs by G. Metaxas. Locals call it St Nicholas the Rich, as wealthy shipowners abroad helped pay for it. It has twin marble bell towers, an imposing staircase and Ionic columns, and inside a carved marble icon screen and bishop's throne by the sculptor Giorgos Vitalis.
Ano Syros
Facing Ermoupoli from the opposite hill, Ano Syros is the medieval settlement of the island's Catholic community and a protected traditional settlement. Whitewashed lanes, arches and stepped alleys climb to the Catholic Cathedral of Agios Georgios (San Giorgio) at the top, a three-aisled basilica. Nearby are the Jesuit monastery and the church of Agios Ioannis, long held by Capuchin monks.
Industrial Museum of Hermoupolis
Spread over four historic buildings, the museum tells the story of the first industrial development in Greece, which took place in 19th-century Ermoupoli. Halls in the main Katsimantis building cover the city of refugees, trade, maritime techniques, Greek steam navigation and the Neorion shipyard, the rise of industry and the making of loukoumi, the island's famous sweet. Tickets EUR 2, reduced EUR 1, free for children up to 12; card payment only.
