The world’s smallest island with a building on it is the Bishop Rock, a skerry off the coast of Cornwall. The islet is 46 by 16 meters, and the tower’s base is 10 meters across. Before the installation of a helipad in 1976, visitors would rappel from the tower’s base to waiting boats.

Among the Thousand Islands at the head of the Saint Lawrence River is the smallest inhabited island in the world, known as “Just Room Enough.” It accommodates a single house.

The “Smallest House in Great Britain” stands on the quay in Conwy, Wales. Built in the 16th century, it has a floor area of 3.05 by 1.8 meters.

Built in 1958, the Little Church in Drumheller, Alberta, is available for ceremonies. It seats six.
