This is a very good museum made up of several component parts set in the grounds of the former Casemate Barracks and its adjacent buildings.
One of the most interesting parts is the restored Commissioner’s House, set over three floors. We made a bit of a mistake and left it till last and ran out of time to see it all as we were not prepared for how much interesting stuff was in there and in the end the museum staff had to finish up chasing us out at closing time. So my advice would be leave plenty of time or do this first.
As a taster, it houses very good historical exhibits including the slavery exhibit and a very good collection of old coins and old Bermudan bank notes. But one of the most surprisingly interesting bits is the newish Grand mural by local artist Graham Foster that now adorns the walls of the main stair case. We spent 30 minutes here alone staring at all the represented aspects of Bermudan history and life.
The Maritime Museum is constantly being upgraded and one of the newer sections is the Shipwreck Island exhibit housed in the Queen's Exhibition Hall on the lower grounds of the Dockyard Keep. Again if your into pirates and stuff from shipwrecks 20 minutes could disappear in here alone.
Then there is the Prisoners in Paradise exhibit in the ammunition High Cave Magazine in the grounds and all this even before you explore all the ramparts and get all the views from the multitude of canons and fortifications, and sneak a look at the Dolphins going through their paces in the Dolphin experience.
On an island where a beer costs $8.50, a $10 entry ticket for all this history is a complete steal.
