Known as Serra da Portela or Serra do Anjo da Guarda, this is a natural viewpoint overlooking the Pousaflores Valley, where the landscape is filled with life and aromas. Wild orchids, rupicolous plants, "cucas" (a type of gourd), wormwood, and the fresh scent of thyme, which wafts away with every step, flourish among the limestone rocks. Here, atop Monte da Ovelha, human presence has left its mark: traditional windmills, a small chapel dedicated to the Guardian Angel, the Stations of the Cross for Good Friday, and initiatives celebrating bread and cornbread. It's also a place made for lingering: sitting at a table, lighting a grill, or simply gazing out.

The Santiago da Guarda Monumental Complex is an unmissable stop, where history unfolds in layers. Classified as a National Monument, it stands out for its Manueline elegance, its 14th-century manor tower, and the impressive Roman mosaics that reveal an ancient villa from the 4th and 5th centuries. The old road between Tomar and Coimbra passed through here, later used by pilgrims on their way to Santiago. Surrounded by the limestone landscape and oak groves of the Serra de Sicó, the place invites you to slow down and take a deep breath. Take the opportunity to chat with the hospitable people.

Penela Castle stands atop the rocky outcrop that gave it its name (peñela, "small stone hill"), dominating the town with imposing walls and towers dating from the 15th and 16th centuries. Founded in the 11th century by D. Sesnando Davides, it formed part of the Mondego defensive line, and its walls still reach 19 meters in height today. From the original fortress arose the castle that later served as a keep. On the walls, facing the Serra da Lousã mountain range, stand out arrow slits and loopholes, marks of its long military life, from arrows to firearms. Penela preserves three historical entrances: the Porta da Vila (Town Gate), the evocative Porta da Traição (Gate of Treason), with its double opening and Moorish inspiration, and the Porta do Relógio (Clock Gate), a reminder of the old breach where two towers collapsed in the 1755 earthquake. In short, a castle small in form, but enormous in history.

The windmills of Corujeiras are a valuable testament to the rural heritage of Sicó. Two types of windmills coexist here: the traditional rotating ones and those of North American influence, dating from the late 19th century, unique in Europe. It is said that an emigrant returning from the United States commissioned the construction of ten of these windmills, of which only five have withstood the test of time, preserving the memory of an ingenuity that crossed oceans.
