The Tbilisi History Museum was founded in 1910 as the City Municipal Museum. More recently, it was given the name of the famous Georgian poet Ioseb Grishashvili. Since 1984, the Tbilisi History Museum has been located in a restored caravanserai, representing the city's historic role as a Silk Road trading outpost. The museum houses over fifty thousand artifacts. They reflect Tbilisi's history from the end of the 4 millennium BCE to the present day. The museum presents archeological, ethnological and archival materials as well as the pieces of national and applied arts, and a rich photo-collection. A number of unique works of artistic and graphic arts are also preserved in this museum. Together with older works, the museum also exhibits pieces of contemporary art. Since 1986, many exhibitions of Georgian and foreign artists have been displayed at the museum.
