Arresø (Danish pronunciation: [ˈɑːɑˌsøˀ]) is the largest lake, by area, in Denmark. It covers 40,72 km² (15.39 sq mi) and is situated on the island of Zealand 43 kilometers (27 miles) northwest of Copenhagen as the crow flies. Arresø is located in the northern parts of Zealand in the region of Hovedstaden just north of Ølsted and east of Frederiksværk. It is a part of the three municipalities Gribskov, Halsnæs, and Hillerød. The lake empties into Roskilde Fjord through the Arresø Canal in Frederiksværk. The artificial canal was begun around 1717 by royal command, and the work was carried out by Danish soldiers and Swedish POWs. There are a number of rivers and streams running into Arresø of which the Pøleå is the most significant. The landscape is especially hilly along the lake's west side. Among these ridges are Maglehøj in the town of Frederiksværk and Arrenakke Hills, which has views of the lake. East of Frederiksværk, the Arrenæs peninsula juts out into the lake. Historically, Arresø was a fjord, having extended northwards as Brødemose Sund, connected to Kattegat, but the land northwest of here rose after the last Ice Age, locking the waters in and creating the lake. Arresø has a rich bird and floral life. Sea eagles have returned as nesting birds, and beavers have been reintroduced. The lake is included in the Kongernes Nordsjælland National Park.The renovated wooden ship M/S Frederikke offers boat tours on the lake between May and September, embarking from Arresødal.

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.
