St. Mark's Clock Tower in Venice is an early Renaissance building on the north side of the Piazza San Marco, at the entrance to the Merceria. It comprises a tower, which contains the clock, and lower buildings on each side. Both the tower and the clock date from the last decade of the 15th century, though the mechanism of the clock has subsequently been much altered.
It was placed where the clock would be visible from the waters of the lagoon and give notice to everyone of the wealth and glory of Venice. The lower two floors of the tower make a monumental archway into the main street of the city, the Merceria, which linked the political and religious centre (the Piazza) with the commercial and financial centre (the Rialto).
The first clock housed in the tower was built and installed by Gian Paolo and Gian Carlo Rainieri, father and son, between 1496 and 1499, and was one of a number of large public astronomical clocks erected throughout Europe during the 14th and 15th centuries. The clock has had an eventful horological history, and been the subject of many restorations, some controversial.
Stairways (steep and narrow) inside the building give access to the terrace on the roof, passing the clock mechanism on the way. Tours (in Italian, English and French) must be booked in advance.References:
Czocha Castle is located on the Lake Leśnia, what is now the Polish part of Upper Lusatia. Czocha castle was built on gneiss rock, and its oldest part is the keep, to which housing structures were later added.
Czocha Castle began as a stronghold, on the Czech-Lusatian border. Its construction was ordered by Wenceslaus I of Bohemia, in the middle of the 13th century (1241–1247). In 1253 castle was handed over to Konrad von Wallhausen, Bishop of Meissen. In 1319 the complex became part of the dukedom of Henry I of Jawor, and after his death, it was taken over by another Silesian prince, Bolko II the Small, and his wife Agnieszka. Origin of the stone castle dates back to 1329.
In the mid-14th century, Czocha Castle was annexed by Charles IV, Holy Roman Emperor and King of Bohemia. Then, between 1389 and 1453, it belonged to the noble families of von Dohn and von Kluks. Reinforced, the complex was besieged by the Hussites in the early 15th century, who captured it in 1427, and remained in the castle for unknown time (see Hussite Wars). In 1453, the castle was purchased by the family of von Nostitz, who owned it for 250 years, making several changes through remodelling projects in 1525 and 1611. Czocha's walls were strengthened and reinforced, which thwarted a Swedish siege of the complex during the Thirty Years War. In 1703, the castle was purchased by Jan Hartwig von Uechtritz, influential courtier of Augustus II the Strong. On August 17, 1793, the whole complex burned in a fire.
In 1909, Czocha was bought by a cigar manufacturer from Dresden, Ernst Gutschow, who ordered major remodelling, carried out by Berlin architect Bodo Ebhardt, based on a 1703 painting of the castle. Gutschow, who was close to the Russian Imperial Court and hosted several White emigres in Czocha, lived in the castle until March 1945. Upon leaving, he packed up the most valuable possessions and moved them out.
After World War II, the castle was ransacked several times, both by soldiers of the Red Army, and Polish thieves, who came to the so-called Recovered Territories from central and eastern part of the country. Pieces of furniture and other goods were stolen, and in the late 1940s and early 1950s, the castle was home to refugees from Greece. In 1952, Czocha was taken over by the Polish Army. Used as a military vacation resort, it was erased from official maps. The castle has been open to the public since September 1996 as a hotel and conference centre. The complex was featured in several movies and television series. Recently, the castle has been used as the setting of the College of Wizardry, a live action role-playing game (LARP) that takes place in their own universe and can be compared to Harry Potter.
