In 1860, Lot Williams, one of Llandudno's first postmen (1841-1919), erected a periscope device on a hill above the Happy Valley. He entertained paying entrants to his 'magic' shed with living panoramas of the town and the bay below. A moving image of Llandudno life and courting couples was cast onto a white circular table in the building by a lens and mirror system mounted on the roof.

It still exists, although rebuilt several times, to this day.
