Constitution Hill, Aberystwyth

Constitution Hill (Welsh: Craig-lais - not the incorrect "Craig-glais") is a hill and historic walking spot found at the northern end of the Aberystwyth promenade, overlooking Cardigan Bay in Ceredigion, Wales, and separating the bay from nearby coastal settlements Borth and Clarach to the north.

Since 1896, the Aberystwyth Cliff Railway, originally the UK's longest funicular railway, has ascended to the hill's summit, upon which there remains a notable Victorian camera obscura, restaurant and small recreation area, known as 'Luna Park'.
