The Tower of David is an ancient citadel located near the Jaffa Gate entrance to western edge of the Old City of Jerusalem. The citadel that stands today dates to the Mamluk and Ottoman periods. It was built on the site of an earlier ancient fortification of the Hasmonean, Herodian-era, Byzantine and Early Muslim periods, after being destroyed repeatedly during the last decades of Crusader presence in the Holy Land by Ayyubid and Mamluk rulers. It contains important archaeological finds dating back over 2,000 years including a quarry dated to the First Temple period, and is a popular venue for benefit events, craft shows, concerts, and sound-and-light performances.
As evidenced by the archaeological discovery of the Broad Wall, King Hezekiah (c. 739 - c. 687 BCE) was the first to specifically fortify this area. The city's fortifications demonstrate that by the late eighth century the city had expanded to include the hill to the west of the Temple Mount. The motivation for building the walled fortification was the expected invasion of Judea by Sennacherib.
The Tower of David Museum is today located in the citadel. The museum presents Jerusalem’s story. It details the major events in its history beginning with the first evidence of a city in Jerusalem in the second millennium BCE, until the city became the capital of the State of Israel, as well as its significance to three religions. The permanent exhibition illustrates the city’s history along the axis of time using myriad methods and includes explanations in Hebrew, Arabic and English.
The Citadel itself is a fascinating archaeological site. The finds uncovered within are a testimony to Jerusalem’s eventful past and produce a representation of Jerusalem and its various historical periods in microcosm. The Citadel’s towers offer a 360-degree view of the Old City of Jerusalem as well as the city’s modern areas.
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.
