Penarth Dock

Penarth Dock was a port and harbour which was located between Penarth Head and the River Ely, at Penarth, Glamorgan, Wales. It opened in 1865 and reached its heyday before World War I, after which followed a slow decline till it closed in the 1960s. The site has since been redeveloped to become Penarth Marina, which now opens into Cardiff Bay.

Harriet Windsor-Clive, Baroness Windsor, whose Plymouth Estate owned vast areas of Glamorgan, formed the Penarth Harbour Company in 1855 with a view to develop a dock for Penarth. She wanted a facility which could rival the new Cardiff Docks which were being constructed a few miles to the north. She was joined in the venture by several prominent politicians and businessmen and, in 1858, engineer John Hawkshaw designed the dock, curving between the Penarth Head and the River Ely. Work on Penarth Dock began in 1859.

The dock was officially opened on Saturday, 10 June 1865. Though Baroness Windsor and her grandson Robert were intended to perform the ceremony they failed to arrive in time for the high tide. The event was carried out by James Poole, the chairman of the Taff Vale Railway, who were the lessees of the new dock. Penarth Dock covered 26 acres and had a 270 feet long entrance lock.

The Taff Vale Railway took a 999-year lease on Penarth Dock, despite having to fight a legal action against Cardiff's Marquess of Bute as far as the House of Lords to enable them to do so freely. They had initially been given incentives to build their railway to Cardiff Docks rather than Penarth. When they went ahead in 1865 and took a lease on Penarth Dock, the Marquess unsuccessfully tried to levy them on their trade from Penarth.
