Pembroke Dock Honours Engineer John Rennie's Memory

A plaque is being unveiled on Tuesday marking the 250th anniversary of the birth of civil engineer John Rennie (1761-1821).

He advised the Navy on the development of a shipyard, choosing the site on which Pembroke Royal Dockyard was created in 1815.

The docks closed in 1926 after launching more than 260 Navy vessels.

Its long history is attributed to the role played by the Scottish engineer.

He is more widely known as a bridge builder, designing Waterloo Bridge in London and Southwark Bridge.

He also designed London Bridge - which was famously moved to Arizona, USA - and which was completed by his son Sir John Rennie after his death.

Stephen K Jones, historic projects consultant for Institution of Civil Engineers Wales, said Rennie senior was deserving of greater recognition.

"Rennie was one of that group of late 18th Century and early 19th Century civil engineers, and although overshadowed by the likes of Thomas Telford and William Jessop, he is a very important engineer in that period.
