The best walks and hikes in Annendaalsbosch

Looked inviting, but was early on the route.

Without a sign, you wouldn't notice the border.

An air watchtower was an observation post used in the Netherlands in the 1950s and 1960s by the Air Surveillance Corps (KLD) to scan Dutch airspace for Russian aircraft during the Cold War. The radar equipment of the time was not yet suitable for fast, low-flying aircraft. The KLD was established to "observe enemy aircraft using observation and listening posts, thus providing the necessary data to combat enemy air attacks and to warn friendly troops and the civilian population in good time of approaching danger from the air." The aim of the service was to be able to observe aircraft up to an altitude of 1,500 meters. A network of air surveillance towers was built to conduct these observations. The air watchtowers were part of a network of 276 observation posts spread throughout the Netherlands. These included 138 posts on existing buildings, such as mills and factories, and 138 freestanding towers specifically constructed for this purpose in the 1950s. . . . . The entire network has never functioned in a wartime situation. With the introduction of jet fighters and radar, the observation system based on the situation in 1940 soon became obsolete. In 1964, the KLD was drastically reduced, after which only a few air surveillance groups remained in the north. In June 1968, the KLD was disbanded. Approximately ten air surveillance towers were handed over to the Civil Defence Service (BB), which used them to locate a possible atomic bomb impact. Bunkers were built on these towers, providing shelter for four people from radioactive fallout. These towers were also demolished in 1980. During the years the network was in operation, a Russian aircraft was sighted. In 1958, observers at Linne Airfield near Montfort in Limburg spotted an aircraft that had participated in a French air show and deliberately deviated from its course on its way back to the Soviet Union to photograph part of the border area. . . . Many of the 138 air watchtowers built were later demolished. Only 19 remain. . . . . Excerpt from https://nl.wikipedia.org/wiki/Luchtwachttoren. A detailed description of the construction and a list of the 19 watchtowers still in existence are also provided there.

https://www.meteotoren.nl/index.php?id=luchtwachttoren-posterholt&lang=en The ruins of the Posterholt Air Watchtower (8O2) are located on the edge of the Nieuw Annendaalsbosch, south of Posterholt, near the German border. The tower is constructed from prefabricated concrete honeycomb elements. At the top of the tower was the observation deck, an open space measuring 3 by 3 meters with a 1.5-meter-high parapet. Unfortunately, all the covering tiles have fallen away, the shelter has disappeared, and the honeycombs are missing. In 1953, a lower tower of approximately 7.5 meters was initially planned and built because part of the surrounding forest still needed to be cleared. However, when the landowner suddenly died, the clearing work was halted, and the engineers raised the tower by more than 3 meters to its current height of almost 11 meters. The air watchtower formed a triangle (air watchtower circle) with the air watchtower in Susteren and the air watchtower in Schinveld (now vanished). The tower was in use until 1964, the year the Air Surveillance Corps in the Southern and Central Netherlands was disbanded. The tower is clearly visible from the hiking trail.

Sit directly opposite on the bench and take a moment to absorb what you have read.

View close to the border between Haaren and Brüggelchen.

This escarpment has been pushed up by the Meuse. The Meuse once flowed here. The highest terrace of the escarpment is at 50 m +NAP.

beautiful view of the mill, the church and the brewhouse of Haaren
