There are woodlands on the southern slope, which are ideal for taking long walks, complemented by the recently created Mediaeval Garden, the first of its kind in Portugal, in homage to the love story between Pedro and Inês. For this garden - where an attempt has been made to create a simple, enclosed environment - around 50 species of plants have been selected, whose existence prior to the Age of the Discoveries can be proven by historical engravings and documents.
