Penmon's veined limestone has been used for centuries in major building projects across the UK. Both of the main Menai crossings, the 1826 Menai Suspension Bridge and the 1850 Britannia Bridge, were constructed using 'Penmon marble', as was Birmingham Town Hall. Postwar reconstruction of Manchester and Liverpool also made extensive use of the stone in the 1940s.

The Great Orme, the headland overlooking Llandudno, dominates the horizon.
