The Old Church Park

The Old Church is surrounded by the Old Church Park. The park worked as a cemetery before the Old Church was built. People began to call it "Ruttopuisto" ("the Plague Park") because the victims of the plague epidemic were buried here in 1710. The plague epidemic in 1710 killed two thirds of the city's residents.

The park's gate, designed by Carl Ludvig Engel, includes a memorial plaque of the fatal year. In the north-eastern corner of the cemetery are the crypt of merchant, Johan Sederholm, and monument of H.C. Reuterskiöld, also designed by Engel.

The last people buried in the old cemetery were those killed in the occupation of Helsinki in 1919.
