The first written mention of the village of Poleň is from 1254. Polen is dominated by the Gothic church of All Saints from the 14th century. In the church, a copy of the painting of the Virgin Mary with Baby Jesus from the workshop of Lucas Cranach is displayed. The original painting can be seen in the National Gallery in Prague. The historic center of the village is declared a village monument zone. In front of the church stands a Polen linden tree, under which the historian Josef Dobrovský liked to sit. Near the church stood the Gothic church of St. Markéty, which is in ruins today. The rectory building, on which there is a commemorative plaque of Polen native Karel Hostaš, the founder of the Klato Museum, is also of architectural interest. The local cemetery with the chapel of St. Salvátor, which serves as the tomb of the priests of Polen, a baroque mortuary and the tombstone of the national revivalist Josef Franta Šumavský. About 2 km from Polena, on top of a hill in a dense forest, the ruins of the early Gothic Pušperk castle are hidden. The castle is surrounded by a massive moat with brick slopes and ramparts.
