This very interesting exhibition is inside the Mon Repos palace and there is an admission of 3 euros.
From the exhibition's flyer:
"John Davenport Shakespear came to Corfu in 1856 as a Major in the British Garisson, bringing with him his bride, Louisa Caroline Sayer. During his stay on the island, he met Edward Lear, a well-known English traveller, painter and humourous poet. The two men became friends and Lear mentions in his diaries that on February 1858 he sold his "photographic machine" to Shakespeare, who combined his military duties with touring the island, capturing unique pictures of the landscape and its residents. The Shakespeare family returned home to England in 1860.
The collection of J.D. Shakespear, which had the chance to survive as a family heirloom, comprises eighty six original photographs. The photographs are ordered, according to the practice of the period, in a usually quite elaborate album. The themes vary. The photographic lens is sometimes focused on the monuments, the public buildings, the harbours, the residences and the streets of city and other times it attempts to capture aspects of the city's suburbs and the countryside. Of special interest are the portraits of the local population and the members of the British community, while particullaty impressive and important for the urban development of the city are the panoramic views."Below are some of the pictures of the exhibition:
