The former Treasury Building was constructed from volcanic rock and Barbados limestone circa 1900. The arch was called the Gateway to the Island because it was the entry to the capital city from the old port. Above the pediment is a beacon that acted as a lighthouse for nearly a century. The heritage building is now home to the St. Christopher National Trust. The institution manages the National Museum. This is an archive of the country’s history and culture dating back to the Indigenous people who lived on the islands before the first European settlers. The exhibits are fascinating to visit.
