The landmark and symbol of Pardubice is the Green Gate, built after 1507, as a remnant of the city's fortifications. It is a Renaissance gate with a façade decorated by a relief designed by Mikoláš Aleš, which depicts the Lords of Pardubice. Behind the gate is a 60 metres high tower that serves as an lookout tower. In its interior there is also an exposition with the history and legends of the city.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
