The construction of Põltsamaa Castle was started in 1272. Between 1570 and 1578 it was the residence of Livonia's King Magnus. Repeatedly pillages, the castle was rebuilt by Woldemar Johann von Lauw in 1770 as a grand rococo-style palace. The castle, and the church built into its cannon tower, burnt down in 1941.
Põltsamaa St. Nicholas' Church was built from 1632 to 1633 on the site of earlier buildings. The nave was built on the 13th century gate buildings and the sanctuary on the 15th century cannon tower. The church was restored by 1952, and the castle ruins came under preservation during the 1970s.
Today the round courtyard holds a tourist information point and several museums including Põltsamaa Museum and a wine cellar with a food museum. There are also an art gallery, restaurant, handicraft and other workshops.
Redipuglia is the largest Italian Military Sacrarium. It rises up on the western front of the Monte Sei Busi, which, in the First World War was bitterly fought after because, although it was not very high, from its summit it allowed an ample range of access from the West to the first steps of the Karstic table area.
