Donostia Diary is a photobook by Peter Bialobrzeski, published by Hartmann Books in 2026. It belongs to his City Diaries, a long-term documentary project begun in 2013 and planned for approximately fifty volumes, in which each book addresses a single city. For this volume Bialobrzeski photographed in Donostia, also known as San Sebastián; the publisher gives the working dates as March 12 to March 20, 2025. The series asks whether the mental image we carry of a city, assembled from prejudice, prior pictures and media representation, can be exchanged for a visual record. Bialobrzeski photographs with a consistent, seemingly objectifying visual language, focusing on architecture, streets and the ordinary conduct of daily life.

The publisher’s note for this title concerns the political memory of the old town. Parts of the quarter were long regarded as strongholds of the separatist movement, and the local adjective etarra is used for those who remained sympathetic to ETA, the terrorist organization whose Gipuzkoa hideout and operational headquarters were located in this old city. The note observes that it is difficult today to imagine that for a majority of the people of San Sebastián the area was effectively a no-go area until ETA declared in May 2018 that it had dissolved its structures and ended its political initiative.

This English-language edition measures 14 × 21 cm and runs to 96 pages with 45 illustrations. The text is by Peter Bialobrzeski, and the design is by Sarah Fricke of Distaff Studio. It is issued as a softcover with flaps, ISBN 978-3-96070-137-8, available from January 2026. The City Diaries volumes are conceived so that individual books can be read on their own or compared with others in the series, such as those for New York or Norderney.
