Ayios Konstantinos ve Ayia Eleni Kilisesi

Ayios Konstantinos ve Ayia Eleni Kilisesi is a Greek Orthodox church with a domed cruciform design and two symmetrical bell towers on its western facade, showing Baroque features. The building contains both the main worship space and renovated accommodation rooms for visitors and researchers.

Construction began in 1856 under architect Konstantinos Karantzas and the church opened in 1861. This period saw Istanbul transforming while different faiths coexisted in the city.

The church is dedicated to Emperor Constantine and his mother Helena, with its icons and liturgical items reflecting Byzantine traditions that continue in this neighborhood. These sacred objects show how the Orthodox faith has been practiced here over generations.

The church is located on Kalyoncukulluk Street in Beyoğlu and is easy to find. The accommodation section provides around 16 rooms, though it is best to check availability beforehand since these may be reserved for specific guests.

The former school building underwent complete restoration in 1999 and became modern lodging facilities. This transformation shows how older religious complexes adapt to new needs while keeping their spiritual purpose intact.
