York Art Gallery’s original Victorian roof space has been opened up for the first time in 60 years.
It was hidden some time between 1945 and 1952 “to create a more controllable environment in which to show works of art”, the York Museums Trust said.
The false ceiling has been taken down as part of an £8m refurbishment.
The roof space will be converted into a mezzanine gallery, which will exhibit the trust’s contemporary British ceramic collections.
The refurbishment project has been funded by donations and grants including £3.5m from the Arts Council England. Once completed, the gallery’s display space will expand by almost 60%.
The additional space will enable the gallery to show more ambitious and high profile exhibitions, the trust added.
