One of the town's more intriguing attractions is the Wilson Museum (tel. 207/326-9247; www.wilsonmuseum.org), on Perkins Street, an appealing and quirky anthropological museum constructed in 1921. This small museum contains the collections of John Howard Wilson, an archaeologist and collector of prehistoric artifacts from around the globe.
His gleanings are neatly arranged in a staid, classical arrangement of the sort that proliferated in the late 19th and early 20th centuries. The museum is open from the end of May to the end of September, Tuesday to Sunday from 2 to 5pm; admission is free.
Next door is the affiliated John Perkins House (same phone number as the museum), Castine's oldest home. It was occupied by the British during the Revolution and the War of 1812, and a tour features demonstrations of old-fashioned cooking techniques. This house is only open in July and August, and only Wednesdays and Sundays (2-5pm).
There is a fee for guided tours of the home. Two additional attractions in the Wilson-Perkins complex (it's almost like a little historical campus, really) include a blacksmith shop and the Hearse House, which are free to tour; both of these outbuildings have the same limited hours as the Perkins House.
Castine is also home to the Maine Maritime Academy (tel. 207/326-4311), which trains sailors for the rigors of life at sea with the merchant marine. The campus is on the western edge of the village, and the 500-foot T.S. (for Training Ship) State of Maine, a hulking black-and-white vessel, is often docked here -- all but overwhelming the village. (It's off cruising to places like Odessa, Germany, and Gibraltar when it's not here.) Free half-hour tours of the ship are offered in summer when the ship is in port.
