Saint Nicholas Church, Mausoleum and ruined church-mosque in Lezhë, Albania

Saint Nicholas Church is a partly standing stone ruin in Lezhë, northern Albania, listed as a Cultural Monument of Albania. The remaining walls are made of worked stone and still bear traces of painted surfaces alongside structural alterations from its later use as a mosque.

Built as a pagan stone structure in the 1st century BC inside an Illyrian city later rebuilt by the Romans, the building became a church dedicated to Saint Nicholas. The League of Lezhë was formed on its grounds in 1444. Ottoman forces plundered it in 1478 and turned it into a mosque with a dikka, a mihrab and a large minaret, naming it after Sultan Selim I.

The building carries several names: Kisha e Shën Nikollës, Xhamia e Selimies, Kisha-Xhami, and, since the 1980s, Skanderbeg Memorial. It was a pagan temple, then a church, then a mosque named after Sultan Selim I, and since 1981 a mausoleum holding Skanderbeg's remains.

The site sits in the center of Lezhë and can be reached on foot from most parts of town. The ground is uneven throughout the ruins, so sturdy footwear makes the visit more comfortable.

During excavations between 1975 and 1980, archaeologists found the Gaviarius stone, a Roman artifact that shows people were already living on this spot long before the church was built. This find places the site within a much longer story of human settlement than its medieval walls might suggest.
