Långe Erik ("Tall Erik") is a Swedish lighthouse built in 1845 and located on a little island, Stora grundet. The island is connected to Öland by a small bridge built in 1965. The older, larger lens is still installed, but no longer in use. The lens was used until the 1990s before an aerobeacon was installed on the lantern's balcony. The light is remote-controlled by the Swedish Maritime Administration. The tower is open for climbing during the summer season for a small fee.
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.
