On 16 September 1941, Soviet forces launched the construction of the Lõpe-Kaimri antitank line to halt the German advance. It runs from west to east in the southern part of the isthmus of Sõrve Peninsula, which is just 3.2 km wide at this point. Comprising two rows of concrete pyramids stretching 900 metres from Lõu Bay to the village of Teesu, the antitank line is in good condition. It is made up of two rows of pyramids standing 0.8 metres high and spaced one metre apart. Parts of the fairly well preserved antitank line have gaps in them, indicating points at which the enemy broke through. The site is easily accessible and can be clearly seen from the road running down the western side of the isthmus. The line is the site of a monument unveiled in 1969, depicting a tall concrete pyramid, which reads: “Lõpe-Kaimri antitank line, built in 1941”.
