An Iron Age residence and a cemetery are also located near the castle. It is not known when Aulanko Castle was built, but it was demolished in the 13th century. At the same time, the construction of Häme Castle began on the other side of Lake Vanajavesi.[2]
The current Granite Castle was built by the owner of Karlberg Manor, Colonel Hugo Robert Standertskjöld in 1887. Flags were hoisted on the towers during celebrations, and salutes were fired from the castle.[3]
Nowadays the Granite Castle functions as a summer theatre.[4]
The Aulanko Castle has developed a diverse and nationally significant cultural environment, which is complemented by the Aulanko Nature Reserve established in the ridge area.[5]
