The older lighthouse of Suurupi was built in 1760. The round old-style stone tower was built near the end of the reign of Czarina Elizaveta Petrovna, this is a magnificent example of classic Russian Imperial lighthouse design. The lighthouse was substantially rebuilt in 1812 and further renovated in 1858. The round watch room was added in 1951, and the present lantern was new in 1998.
The newer wooden lighthouse date back to the year 1859. It is 15 m high, square pyramidal, 4-story wood keeper's house with A-frame roof and painted in white. The light was formerly shown through a window on the top floor at one end of the building; it has been moved outside to the windowsill. A miraculous survivor of two world wars and over 150 winters, this remarkable lighthouse is a well-known historic landmark on Estonia's coastline. The top floor with its lantern chamber was added in 1885, increasing the tower height by 3.5 m.

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.
