Osborne House is a stately home in Cowes, Isle of Wight, UK.
The house was commissioned by Queen Victoria and Prince Albert and was built from 1845 - 1851. It was at Osborne House that Marconi and Alexander Graham Bell first demonstrated the telephone to Victoria, in 1878, and Marconi later transmitted radio messages to Victoria to keep her up to date about the state of health of her son, Edward.
The house was a favourite of Victoria, who spent many summers there. Following Albert's death in 1861, she effectively made it her permanent residence.
The house is now owned by English Heritage and is open to the public.
