 In the summertime, the government holds its informal evening sessions at Kesäranta.These take place on Wednesday evenings and date back to the 1930s, when Prime Minister Aimo Cajander adopted the practice of inviting ministers to Kesäranta to discuss and prepare matters to be handled in the Government plenary session on Thursday.A thorough renovation of the main building took place first in the 1950s and again in the 1980s.
