The architectural highlight of the Barbados Garrison Historic Site is the Main Guard House. The Georgian-style building served as a military courthouse, jail and command post for more than one hundred years, from 1803 until the British forces left the island in 1905. The outstanding features are the red brick clock tower and the coat of arms for King George III above the entrance. If you are in the area on a Thursday, stop by at noon. You will be delighted to watch the changing of the sentry. The soldiers wear Zouave uniforms of the West Indies Regiment from 1858.
