Maarjamäe Castle, part of the Estonian History Museum, offers an engaging visit into Estonia's modern history. The main palace and its exhibitions are largely accessible, featuring ramps and lifts, while the expansive park grounds are also easy to navigate. Visitors can explore independently at their own pace, or opt for guided tours to deepen their understanding. While the outdoor park and Memorial of the Victims of Communism are always accessible, the palace's indoor exhibitions have seasonal opening hours, typically shorter in winter, so checking the official website is advisable. Expect a moderate entry fee for the museum, generally in the €8-€15 range, with the park and memorial free to explore. A typical visit to the palace exhibitions alone takes 1.5 to 3 hours, but factoring in the sculpture park, memorial, and scenic grounds can extend the experience to 3-4 hours, providing panoramic views of Tallinn Bay and a café for refreshments.
