Heritage Open Day: An exhibition of drawings and maps created by Nicola Crowson and Tina Bird Wallbridge Of The School of Architecture, Art & Design, University of Portsmouth. Site Lines and Motifs is a public exhibition that invites visitors to explore the city of Portsmouth through a new lens—one shaped by memory, narrative, and place. For a limited time, the ground floor of Storehouse 9 in Portsmouth Historic Dockyard will be open to the public, transformed into an immersive space of drawings, maps, and projections that uncover the hidden stories of the city.
