Bastion Powder Cellar Infrastructure
The powder cellar (warehouse) building in the courtyard of Bastion 7 was built in 1859–1861. Inside the building, under the massive brick vault, there were two rows of wooden scaffolding shelves on which powder barrels were stored.
During the Soviet period, the building was used for storing and preparing vegetables, salting cabbage and pickling cucumbers in large concrete tubs for the military school canteen.
In 2020-2021, the building was renovated and the surrounding area was improved. On April 22, 2022, a new exhibition space was opened in the building – Martinsons House, dedicated to the creative work and legacy of Daugavpils-born ceramist Pēteris Martinsons (1931-2013), which includes 340 works – ceramics and ink drawings. Some of them can be viewed in Martinsons House, which is part of the Mark Rothko Art Center.
