In 1853 Rev. William T. Collings became Seigneur of Sark, his mother, Marie, having only been Seigneur for less than a year before her death.

Collings was keen on improving the welfare of the community and sought to encourage the newly developed industry of tourism.

To this end he had a window cut into the cliff, framing the view of Port Du Moulin Bay Arch and Les Autlets. By the 1870s, Sark had around 5k visitors a year.
