The Battery Carriage Inn on South Battery was recently renovated to include the whole house as part of the inn. Some of its more frequent guests over the years have been ghosts — which have been repeatedly seen. One of the more scary ones is a headless torso, but a more polite one is known as the “Gentleman Ghost.” If you want to check it out for yourself, they are known to hang out in specific rooms. So, make sure you request them when you make your reservation. Or not.
