Ein Hemed is a national park and nature reserve in the hills seven kilometres west of modern Jerusalem. A fortified Hospitaller building from the Crusader period, relatively well preserved, is arguably the main attraction beside the streams and lush vegetation.
The Kingdom of Jerusalem built fortresses along the road to Jerusalem in order to control the traffic to Jerusalem, and protect pilgrims visiting the Holy City. Farms were built using the spring water for irrigation.
Impressive ruins of a 30x40 metre Crusader courtyard building, whose southern wall survives to a height of 12 metres, are located on the north site of the riverbed. The building has several gates and two arched halls. Archaeological investigations indicate that it was built in 1140-1160, during the reign of Fulk of Jerusalem, in the same period as the fortresses on Tzova and Abu Ghosh. South of the building are a nature reserve and a Muslim cemetery.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
