Peter the Great’s house is the oldest museum in Tallinn that opened its doors in 1806. Peter I and Ekaterina I stayed in this house during their visits to Tallinn from 1714 to 1723.
The tsar first visited the house at the height of the naval campaign in 1714. It was located on the slope of the hill overlooking the city and the sea, and thus allowed Peter I to track the course of the Swedish ships approaching the city. In 1715, the manor house was purchased by Peter from a widow of a town alderman for 1400 rubles. In a small garden next to it, flowers and herbs were planted.
Alexander I’s visit to Tallinn played an important role in preserving Peter’s heritage. Following the emperor’s order in 1804 the house was renovated and opened as a museum in 1806. Starting from the 19th century, the museum was popular among locals and guests of Tallinn.
