The Rock Hotel, also known as Rock Hotel, is a historic hotel in the British Overseas Territory of Gibraltar. It has been described as "one of the Mediterranean's most famous hotels," and as "an institution in Gibraltar and the Mediterranean." Built in 1932 by John Crichton-Stuart, 4th Marquess of Bute, the hotel is set in a 3.6-hectare (8.9-acre) landscaped garden and contains 104 rooms. It is located in a large white Art Deco building along Europa Road, overlooking the Gibraltar Botanic Gardens.HistoryEarly yearsThe Rock Hotel was built by John Crichton-Stuart, 4th Marquess of Bute, and began operation in 1932. In the years after it opened, the hotel was managed by Rudolph Richard and earned a reputation as one of the finest hotels in Europe. Its notable guests included Sir John Mills, Winston Churchill, and Errol Flynn.During the 1930s and '40s, the hotel provided visitors with a first-hand perspective on the area's military activities. During the Second Italo-Abyssinian War, visitors could watch as Britain's Royal Navy engaged in manoeuvres off the coast of Gibraltar. American journalist Westbrook Pegler stayed at the hotel and took movies from his balcony of the British fleet engaged in exercises. In November 1935, Pegler reported that the hotel's management instructed guests to leave the full-length glass doors open while a new gun on the HMS Hood, the largest warship afloat at the time, was tested. He noted that the hotel's balconies "afford a fine view of the pageant of peace" and described "a mighty thump that popped eardrums and rattled glasses on the bathroom shelf" of his room at the Rock Hotel.
