Classic church from 1838. The building was designed by Augustus Smith himself. The window details are beautiful: there is a crab basket above St. Christopher and a lighthouse in the window next to it.

There is a hotel in the Star Castle. But you can climb the ring of walls and admire the view.

Beautiful castle overlooking the water. In general, it's nice to walk across the island, the sailing boats in the bays, the lively ferry traffic, the harbor lies like a beehive, the awareness of being here in the middle of the Atlantic. A dream.
