Agger Tange
Coordinates: 56 ° 43 ′ 51.2 " N , 8 ° 14 ′ 8.3" E
Agger Tange is an 8.5 kilometer long spit in the southwest of the Danish island of Vendsyssel-Thy . The headland lies between the North Sea and the Limfjord and includes the area between the village of Agger and the Thyborøn Canal .
Most of Agger Tange is a nature reserve, which, along with the surrounding waters, is designated as a protected wetland in accordance with the Ramsar Convention . In addition, the area belongs to the European bird sanctuaries as well as to the EU protected areas in terms of the Fauna-Flora-Habitat Directive .
Coastal dunes run parallel to the North Sea to the west , while salt meadows are located on the eastern side facing the Limfjord . The southern tip of Agger Tange, Svanholm , grows in a southerly direction through steady sand deposits. Due to coastal erosion , the headland loses up to nine meters of land annually to the west. Prewashing sand and 29 groynes at a distance of 400 meters each are intended to slow down this process. The longest groyne is located directly at the entrance to the Thyborøn Canal and is over 800 meters long.
From the village of Agger at the foot of the Agger Tange to the tip of the headland, there is a 9-kilometer-long, dead straight road, secondary route 181 , which is also part of the North Sea Cycle Route . It ends at a ferry pier, the ferry connects Agger Tange with Thyborøn on the opposite headland Harboøre Tange .
Breakthroughs after storm surges
As early as the Viking Age, the North Sea broke the narrow land bridge between Thy and the rest of Jutland several times , making the Limfjord navigable seaward. For example, Canute the Great passed Agger Tange in 1027 on the way from England to Denmark. The passage initially silted up around 1100, but tore open again and again in the following centuries - documented for the years 1560, 1572, 1586, 1624, 1656, 1685, 1825 and 1862.
Agger channel
During the storm surge of February 3, 1825 , the Aggerkanal was created , which was three kilometers north of today's Thyborøn Canal . The current between the North Sea and the Limfjord was so strong that the canal was 440 meters wide in 1849. In 1834, nine years after the disaster, the first ships passed through the canal. The breakthrough of the North Sea led to a strong upswing for trade and marked growth for the cities in the western Limfjord. In 1855, 1,800 ships passed the canal, which however gradually silted up again. After a storm surge in 1862 that created the Thyborøn Canal, shipping through the Aggerkanal was abandoned in the mid-1860s, and it was closed in 1875. Its function was taken over by the Thyborøn Canal, which has since been kept open by coastal protection measures. Remnants of the Agger Canal are still visible to the east of Agger Tange.
