Alexandra Battery is a fortification made in the 1860s. Just below the fort, there is a small beach which is well known in Bermuda for colorful sea glass.Alexandra Battery is on Barry Road in St. George’s Bermuda. It’s about 30 minutes walk from the St. George’s cruise terminal. On your way to the beach it would be a little uphill, but the walk is beautiful and scenic. We have always enjoyed it. If you are planning to make heavy collections of sea glasses from the beach, the walk back can be strenuous, although it would be downhill on your return.
