Entrance to the Grotto of Antiparos 16 May 1862. Francis Bedford (1815-94). The Prince of Wales described his visit: ‘A ride of 45 minutes brought us to the entrance of a large grotto or cave which is 60 fathoms in depth. We descended it by means of rope and rope ladders, and it was by no means an easy job. … There are some very fine stalactites in the cave.’ Acquired by the Prince of Wales, 1862.
