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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
