An important locality from the Viking age and up to its days as a royal castle from the 12th to the mid-16th century when it was disbanded following the Count's Feud civil war. Many of the stones were used during the construction of Kronborg castle in Helsingør. The moat and ground layout of the old castle is still visible
Søborg Castle is a ruined castle south of Gilleleje in North Zealand, Denmark. It was one of the strongest castles in Denmark and was also used as a prison. It was inhabited until the Count's Feud in 1535, when it is speculated that it was destroyed. In 1577, the feudal tenant was granted permission to use the ruins as a quarry.

A 9-km canal between Esrum Sø lake and the north coast at Dronningmølle, built in 1805 to transport timber from the forests to Copenhagen. The canal lost its importance when the railway was built, and was subsequently abandoned. However, it is still visible in the landscape, and while partly overgrown, parts still carry water and many of the old installations related to the canal is still there. The trail where horses used to haul the prams along the canal, still exists, and offers a fantastic walk.
A historic 65-meter hill-top in the middle of the forest, which towers (well, at least for Denmark) above the surrounding area's and offers some nice views over Northern Zealand. The site was home of the massive fruebjergmødere gatherings at the turn of the 19th century, closely related to Grundtvigs folk high school movement. A tradition that has been revived.
