The Land where Lulworth Castle now stands was first acquired by Thomas Howard, son of the 2nd Duke of Norfolk by marrying one of the last of the de Newburgh family. Also acquired at this time was land at the Bindon Abbey Estate. In 1575 Queen Elizabeth made him Viscount Bindon and in the same year Thomas built a large country house on the site of Bindon Abbey. Thomas was a wealthy man who held high office at the time, including that of Vice Admiral of Dorset, and defender of the Dorset coast against smuggling and piracy.

Over the years, the castle has seen a number of uses, occupants and a varied and colourful history. There have been a number of significant events at the Castle, some like the fire of 1929 were devastating, others less so but equally as important in the Castle's history.
