A prototype preservation was carried out on a 45-feet high and 30-feet wide panel on the western segment of the Picture Wall by Aga Khan Trust for Culture (AKTC) and the Walled City of Lahore Authority (WCLA). This preservation process started in 2016 and was completed in December 2017. The workshop was a follow-up on the prototype.
