St. Tudno's Church and Graveyard - Conwy
The original Church was built in the 6th century, but non of the original building remains now. The current Church was built around the 12th century with further extensions around the 15th century.
In 1839 the roof was damaged in a storm and another Church was then built in the centre of Llandudno instead of repairing it... until 1855 when it was restored.
