Located in the middle of Riga's Old Town in the old Powder Tower, is one serious war museum. The tower itself has a long history spanning back to the beginning of the 14th century. It was destroyed by invading Swedes around 1621 and rebuilt 30 years later and it has housed the museum since 1919. The red brick tower is easy to find and is a beautiful building with climbing ivy covering parts of the wall. It doesn't look really big from the outside and I was therefore surprised when I exited the museum realizing I had spent nearly 3 hours there. It's a huge exhibition covering Latvia's military history from the 11-1200 A.D., but with most of the focus on 20th century conflicts. It is open daily and has free entry. Well worth a visit if in Riga!
