The Castle of Soave is a typical medieval military edifice, commanding the neighbourhood of the city from the Tenda Hill. It comprises a mastio (donjon) and three lines of walls forming three courts of different size. The outer line, with a gate and a drawbridge, is the most recent, built by the Venetians in the 15th century. It houses the remains of a small church from the 10th century.
The second and larger court, the first of the original castle, is called della Madonna for a fresco portraying St. Mary (1321). Another fresco is visible after the door leading to the inner court, and portrays a Scaliger soldier. The mastio is the most impressive feature of the castle. Bones found within showed it was used also as prison and place of torture. The House called del Capitano (the Scaliger commander) houses Roman coins, weapons parts, medals and other ancient remains found during the most recent restoration. Adjacent is a bedroom with a 13th-century fresco with St. Mary and Madeleine and a dining room with medieval kitchenware. Another room houses the portraits of the most famous Scaliger figures: Mastino I, Cangrande, Cansignorio and Taddea da Carrara, wife of Mastino II; the portrait of Dante Alighieri testify an alleged sojourn of the poet in the castle.
