N.P. Wieth-Knudsen Observatory is next to Tisvilde Hegn, two hours away from Copenhagen, Denmark, at Margot Nyholms vej 19, 3220 Tisvildeleje, on the outskirts of a small residential area in Tisvilde, away from artificial light generated by larger cities. It was constructed in 1959 by Dr. Niels Palle Wieth-Knudsen (1909–1993), who used the observatory until his death. His biggest contribution to astronomy was the observation of lunar occultations, during which the moon passes in front of stars, the data from which is then used in the accurate determination of the lunar position. This became important during the 1969 Apollo Moon landings.In 1999, Wieth-Knudsen's widow, Inger Wieth-Knudsen (1914–2004), presented the building as a gift to the Danish Astronomical Society. The observatory holds a 16-inch computer-controlled telescope. On the observatory grounds there are two radio telescopes and a series of platforms for smaller telescopes, including a solar telescope. The public is welcome to free star-gazing events held on the second and the last Saturdays of every month. Members of the Danish Astronomical Society use the observatory for their own observations on other nights.

Asserbo Charterhouse
Asserbo Charterhouse

Asserbo Charterhouse is a fortress and Carthusian monastery ruin in the small town of Asserbo north of Frederiksværk on North Zealand in Denmark. The monastery was founded by Bishop Absalon in the later part of the 12th century and functioned as a short-lived Carthusian monastery. It later came under Sorø Abbey and parts of it under Esrum Abbey and remained so until the end of the middle ages. In that period the buildings were used as a farmhouse or small manor and administered as a so-called Grangier (farmhouse and nearby buildings) by the monks of Sorø Abbey. Originally it comprised a main building, a tower with a cellar, various cellars and some half-timbered houses. The buildings were founded on a structure of large bricks, known as monk bricks. The site was surrounded by an embankment and access was only possible by a drawbridge from the north side. In 1248 we know from written sources, that Asserbo Chartehouse had developed into a small village, the village now known as Asserbo. From the 15th century Asserbo charterhouse was leased to various noble families, until Steward of the Realm Poul Laxmand took ownership in 1490. From then on, the ownership shifted between The Crown and various noble families until the start of the 18th century, when it was left to the devastating drifting sands of the time. The drifting sands and dunes were eventually stopped in the 1730s and covered by the plantation of Tisvilde Hegn (English: Tisvilde Fence). The charterhouse was dug free in 1849 and the embankments were restored in 1972.
