Petäjävesi Old Church, in cen­tral Fin­land, was built of logs between 1763 and 1765. This Luther­an coun­try church is a typ­i­cal exam­ple of an archi­tec­tur­al tra­di­tion that is unique to east­ern Scan­di­navia. It com­bines the Renais­sance con­cep­tion of a cen­tral­ly planned church with old­er forms deriv­ing from Goth­ic groin vaults.
