Stratigraphy Diagram of Rāmera Tower

This diagram shows the stratigraphy beneath Rāmera Tower, part of Riga’s medieval defenses. Excavations (1971–73) revealed: 1. Construction debris – from building or repairs. 2. Organic-rich layer – signs of earlier activity. 3. Light sand – possibly for leveling. 4. Pit trench – for the tower’s foundation. 5. Grey loam – compact support layer. 6. Peat – traces of former marshland. 7. Gravel – stable base. The profile reflects how Riga’s fortifications were adapted to soft, layered terrain.
