The Tordenskiold Oak (in Norwegian:Tordenskioldeika) in Kjølhalskogen in Horten, Norway is one of the oldest trees in Norway. The tree trunk is very hollow, so the tree is almost split in two. The oak was protected by a royal decree on December 9, 1921. It is not possible to say how old the tree is, but it goes for at least 800, maybe close to 1,000 years. The tree has been supported and bolted to hold the trunk together, and a fence has been set up around the tree as a hedge on the day it falls. The biggest threat to the tree was in 1993, when it was discussed both to lift the conservation and to have the heavily enclosed tree removed. Local environmental protection authorities were concerned about the safety, but lacked the financial means to take adequate security (fencing). However, these plans led to great local involvement in the city, and much publicity in the local newspaper Gjengangeren, where a fundraising event was discussed. At that time, former Mayor Jon Brekke pointed out that oak represents an important part of the city's identity, and is a very important cultural heritage worth preserving.

Citadellet (Citadel) was a 19th-century Norwegian fortress. The last day of military activity was in 1970. The fort was demolished in 1971. Citadellet was intended to protect the Royal Norwegian Navy's Karljohansvern naval station in Horten. Karjohansvern was the main base for the Royal Norwegian Navy from 1819 to 1963. The fortress was built between 1848 and 1851. Its architect was Christian Heinrich Grosch (1801-1865). The fort were established in conjunction with Norske Løve Fortress which was built between 1852 and 1859. Specific plans for the design of both fortifications were first completed in the mid-1830s, based upon designs largely begun in the 1820s. The forts were expected to assume a key role as defender of the fleet and defense against attacks from the sea.

Norske Løve is the name of a 19th-century fortress built from 1852 to 1859 to protect Karljohansvern naval station at Horten in Norway.
