This collection brings together the sketches, architectural drawings, and correspondence for the projects architects Harika Söylemezoğlu (1918-2020) and Kemali Söylemezoğlu (1909-1995) undertook, as well as the couple’s personal materials and travel photos from various cities. Including a significant group of documents relating to the work of architect and educator Paul Bonatz in 1940s Turkey, the collection acts as an important source of reference for this period.
