Guernesy is of great archaeological interest due to the dolmens and menhirs that dot the island, the largest of these being La Varde Dolmen. Situated on the crest of the hill on the west side of L'Ancresse common, between Grande Havre and L'Ancresse Bay, and north of Mont Cuet Road. For Grey was originally detached from the shore, the rocky islet on which the present fort stands was the site of the much older Chateau de Rocquaine. The concentric stone battery with positions for six 24 - pounder iron guns of the Napoleonic period, surmounted by the squat Martello tower of 1804 now housing the Shipwreck Museum. Hauteville House,located at 38 Hauteville, was bought by Victor Hugo in May 1856, thanks to the success of "Les Contemplations". Victor Hugo actively took part in fitting it out and decorating it, to such a point that his son was able to write that it was "a veritable autograph on three floors....... like a poem in several rooms". Guernsey Museum and Art Gallery was purpose-built in 1977 to house the collections previously on show in the Lukis and Island Museum. It is designed to compliment the octagonal Victorian bandstand and in 1979 the museum was chosen as the British "Museum of the Year". In 1993 the museum was extended and refurbished.
