The interior of the first floor of Mulchowk houses Architecture Galleries, an ongoing extension of the Patan Museum. Historical windows, columns, struts, tympana, and other artefacts are displayed in a typological order, accompanied by drawings and written commentary. Once completed, the galleries will include a media room and additional exhibitions in the north wing of Mulchowk and the east wing of Sundari Chowk showcasing architectural drawings and fascimiles of historic paintings.
