Prince Charles celebrated his own 60th birthday earlier this year, and so he was on hand to mark another diamond event – the Land Rover anniversary.
The Solihull factory marked the occasion with a Land-Rover-shaped cake and the unveiling of a plaque.
The Prince had a tour of the factory, with models from the launch of the factory up until the current model range on show.
Phil Popham, managing director of Land Rover, said: "It is a great honour to play host to the Prince of Wales at such a significant milestone for the company.
"Land Rover has played an important role within the British car industry for 60 years and we strongly believe that it will continue to do so for many years to come."
Earlier this year, the Land Rover and Jaguar marques were bought by the Indian Tata company. They are continuing to support a £700 million investment in reducing CO2 emissions using hybrid technology and introducing lighter weight materials into the range.
