We don't visit many museums on our travels but we had a 1/2 day left in Belize City before catching our flight back to Canada. The Museum of Belize gets very good reviews and was short walking distance from our hotel.
The building that houses the museum was built as a prison between 1854-1857 and housed prisoners until 1993. It was restored and renovated in 2002. They have retained much of the original building and you can see where the cells used to be by the bars above each of the openings.
In addition to the prison history, exhibits include Maya artifacts and history, insect and bird displays, and an art exhibit. Also on display was a Belize flag "recovered from the rubble of the World Trade Center on September 11, 2001, and stands as a reminder of that tragic morning. It is one of the few that were discovered after the tragedy. The flag was salvaged by the New York City Fire Department who then gave it to the Embassy of Belize in New York. It was later donated to the Museum of Belize."
By far the most depressing part of the museum was the slavery exhibit. Some of the stories depicted are truly awful and it's hard to grasp human beings treating others so badly. Really, I don't have the words for it. It's mind boggling to think this went on for more than 400 years.
