I didn't know that an Italian Archaeological Mission was established about sixty years ago in Swat at the request of the Wali of Swat. This archaeological mission has been continuously excavating the Buddhist sites in Swat valley al this time. This museum was primarily built to house the artifacts they excavated.
Please google Italian archaeologist Dr Luca Maria Olivieri. He was awarded the prestigious Sitar-e-Imtiaz prize by the President of Pakistan, Mamnoon Hussein, as an acknowledgement of his work in the Swat Valley. A great collection.
The museum has calming energy. Never crowded. The staff is very knowledgeable. One of them has been there for more than 40 years. They jokingly call him the 3rd Buddha :)
