Castellani House is a large nineteenth-century building in Georgetown, Guyana. It is on the corner of Vlissengen Road and Homestretch Avenue (by the Botanical Gardens). It was designed and constructed by the Maltese architect, Cesar Castellani, between 1879 and 1882. Originally serving as a residence for colonial government officials, Castellani House has been the home of Guyana's National Art Gallery since 1993.[1][2][3][4][5]
