So called because of the 18th century frescoes on the ceiling depicting a series of pairs of lions, brought to light during the refurbishment.
The bed is made of wrought iron designed to resemble the models of the able 18th century blacksmiths of Pienza (an enchanting medieval town to the south of Siena). The bedroom is endowed with a splendid (non-functioning) fireplace which was discovered and restored during the refurbishment.
