Syros, Agios Nikolaos in Ermoupolis, Orthodox church building in Ermoupolis, Greece

Agios Nikolaos in Ermoupolis is an Orthodox church featuring two bell towers and a bright blue dome visible from across the city. A 4-meter (13-foot) staircase leads to the entrance, placing the building on a raised platform above street level.

The municipality decided in 1841 to build a new church; in 1847 L. Zavos made a wooden model, and G. Metaxas's final plan was engraved to attract donors. King Otto personally signed the plans, ratified by royal decree in 1851. The foundation stone was laid on 28 February 1848 by Metropolitan Daniel Kontoudis, and the church was inaugurated on 14 September 1870 by Archbishop Alexander Lykourgos, before the interior decoration was finished.

The church bears the name of Saint Nicholas, patron of seafarers, reflecting the maritime roots of this island community. Inside, artworks from the 1800s showcase the skill of Greek artists and craftspeople of that era.

The church sits near Miaouli Square in downtown Ermoupolis, making it easy to reach on foot from the harbor area. Visitors should expect regular religious services, so timing your visit between services allows better access to the interior.

The marble iconostasis was made by sculptor Georgios Vitalis between 1883 and 1899 from Pentelic marble, with Italian marble inlays in the frames and base, after a nationwide competition the municipality announced in 1871; its designer is unknown. The marble ambo, donated by D. Vafiadakis in 1868, was designed by Ant. Frangoulis following the ambo of the Athens Metropolitan Cathedral.
