Martello Tower 2 is open to the public only during staged events, like the Convict’s Last Drink . This lively interactive theater (in English) gives a taste of 19th-century justice. It features a mock trial of a soldier accused of a crime, and the audience will decide his fate while – and this is the important part – sampling homemade beers. Because alcohol is served, those under 18 must be accompanied by an adult; reserve through the Discovery Pavilion or by phone. A French-language version (La Dernier Verre) takes place at 6:30pm daily (mid-July to early September). Other shows include an ‘1814, council-of-war-style’ feast (adult/child $35/32), during which diners must discover who among them is the ‘traitor.’ It’s in French only, but there are translated scripts so English speakers can follow along. Call for a schedule. Reserve ahead.
