Lecce
"Torre del Parco ("Park Tower") is one of the medieval symbols of Lecce. It was erected in 1419 by the then-18 years old Giovanni Antonio Del Balzo Orsini, prince of Lecce. The tower, standing at more than 23 metres (75 ft), is surrounded by a ditch in which bears (the heraldic symbol of the Orsini del Balzo) were reared. The whole complex was the seat of Orsini's tribunal and of a mint, and after Giovanni Antonio's death, it became a residence for the Spanish viceroys." Wikipedia
