Excerpt: Excavation of Shahi Hamam was started by WCLA in November 2013 in collaboration with the Agha Khan Trust for Culture and international excavators started working on the project. WCLA officials said in 1955, Shahi Hammam was recognized as a cultural asset and declared a protected monument by the Department of Archaeology. The entrance gateway on the west and the main hall in the northern part of the building are exquisitely decorated with frescoed panels depicting angels, animals, birds, floral and geometric designs.
A detailed report compiled by WCLA on the project revealed that having been covered for decades, if not centuries, with successive layers of whitewash, the frescoes were uncovered in 1991 and found to be unaltered specimens of Mughal era wall paintings, although a little provincial in execution.
