Despite its purely Baroque appearance and its name from the 15th century Swedish king Gustav I, this church was built only in 1906.
St George's Church was completed in 1890. It was designed by the architect Anders Gustaf Forsberg for the Catholic Apostolic Church, which retained the building until it was handed over to the Greek Orthodox in 1978. The church, in Gothic Revival style, is a long, single-naved church with red brick facades, patterned cornice and mouldings, and grey cement surrounds.
Built in the 18th century to replace a older wooden church in the same place. Its cemetery is where René Descartes was first buried in 1650, before his remains were moved to France. There is now only a memroial to him inside the church.
