Remains of a medieval tower located in the hamlet of Pogi, near the little church of San Giovanni. The evidence consists in a whole portion of a tower that collapsed downstream from the current settlement. The tower is realized at sack, with rough-hewn stone facing placed on horizontal courses. Given the internal dimensions, a residential use of the structures is excluded, probably his only function was defensive; a particular aspect was its position, located outside the castle walls. Through the analysis of the masonry technique we can date this element to a generic period between the 12th and 13th centuries.
