The dome of Agios Nikolaos’s church is distinguished everywhere and when you enter its interior you will feel the wonder. It was founded in 1849 in designs by G. Metaxas, and it was inaugurated in 1870. It is cruciform and mounted on an elevated courtyard with marble parapet. It belongs to the type of domed basilica. A staircase 4 metres high leads to the full-marble central section of the façade, which has propylon in the form of portico in four Ionic columns and pilasters with Corinthian capitals on the ground floor.
The marvelous concealed lighting and the crystal chandeliers from Trieste highlight every elaborate detail, the famous marble iconostasis with icons of 1909, the despotic throne that Tinian marble sculptor G. Vitalis made, the pulpit, the icon of Agios Nikolaos, the Epitaph, the space where the ecclesiastical choir chants hymns from 1920 up to today. The icons on both sides of the Beautiful Gate are works of Mount Athos’s monks and they were created in the early 20th century. The Last Supper and the Descent from the Cross above the Great Gate are works of Russian hagiographers.
