Originally a signaling station for communicating with ships anchored in the harbor, this handsome building on top of Observatory Hill is now an astronomy museum. Within its sandstone walls, hands-on displays—including constellation charts, talking computers, and games—illustrate principles of astronomy. During evening observatory shows you can tour the building, watch videos, and get a close-up view of the universe through a 16-inch mirror telescope. Reservations are required for the evening show. Times vary depending on the season.
