The Orto Botanico dell'Università di Pavia is a botanical garden maintained by the University of Pavia.
The garden was begun in 1773 as a successor to Pavia's earlier Orto dei Semplici (established 1558). By 1775 the garden was in use, with its first wooden greenhouses constructed in 1776. Nocca Domenico organized and expanded the garden 1797–1826, adding collections to exchange seeds and plants, and building a masonry greenhouse to replace the earlier wooden structures. The garden was extensively damaged in World War II, after which its greenhouses were relocated to the main building's south side.
Today the garden contains about 2000 taxa, with major collections of aquatic plants, conifers, hosta, hydrangea, magnolia, medical plants, peat bog plants, and a rose garden.
References:Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
