The ir. D.F. Woudagemaal is the largest still operational steam-powered pumping station in the world. On October 7, 1920 Queen Wilhelmina opened the pumping station. It was built to pump excess water out of Friesland, a province in the north of the Netherlands.
In 1967, after running on coal for 47 years, the boilers were converted to run on heavy fuel oil. It has a pumping capacity of 4,000 m³ per minute. The pumping station is currently used to supplement the existing pumping capacity of the J.L. Hooglandgemaal in case of exceptionally high water levels in Friesland; this usually happens a few days per year.
Since 1998 the ir. D.F. Woudagemaal has been listed on the UNESCO World Heritage Site list. The station is open for visitors and tours are given regularly.
References:The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
