Müggelheim

The Berlin-Müggelberge TV tower is the 31 metre tall base of a tower, never completed, in the Müggel hills of southeast Berlin, Germany. The tower base is currently used as radio relay link station. The tower was originally planned as the TV tower for Berlin. It was to have a total height of 425 feet (130 meters) with an observation platform at 230 feet (70 meters). After construction was started in 1954, a survey indicated that the tower would endanger aircraft on approach to the Berlin-Schoenefeld airport. For this reason, on 13 December 1955 construction was stopped. The tower base was later used by the East German Ministry for State Security (Ministerium für Staatssicherheit or Stasi) as a listening post. Today it serves the Deutsche Telekom AG as radio relay link station and has a radar dome on its top. Close to the tower, there is a 64 metre tall lattice tower with aerials for non-public mobile radio services and directional antennas. The Berlin-Müggelberge TV tower is not accessible to the public and is not to be confused with the Berlin-Müggelberge look-out, known as the Müggelturm (Müggel tower), which is publicly accessible.

The Müggelberge (also formerly called the Müggelsberge) are a wooded line of hills with heights up to 114.7 m above sea level (NHN) in the southeast of Berlin's Treptow-Köpenick quarter. They are dominated by the Kleiner Müggelberg (88.3 m) and Großer Müggelberg (114.7 m). The Müggelberge cover an area of around seven square kilometres. The ridge was formed during the ice age. A viewing tower called the Müggelturm has been erected on the hills with a view of the Müggelsee and the Berlin-Müggelberge TV Tower.

The Langer See is a lake situated in the south-eastern outskirts of Berlin, the capital city of Germany. The lake is aligned south-east to north-west and forms part of the course of the River Dahme. The Langer See is approximately 11 kilometres (6.8 mi) long, with an average width of 221 metres (725 ft) and an area of 2.43 square kilometres (0.94 sq mi). The Dahme flows into the Langer See from the Zeuthener See, at the south-east end of the lake by the Berlin suburb of Schmöckwitz. It flows out to the north-west near Köpenick and its confluence with the River Spree. At Schmöckwitz the Langer See also mingles with the Seddinsee. Like the River Dahme, the Langer See is navigable. Besides traffic to the upstream reaches of the Dahme, the lake also carries traffic to the Oder-Spree Canal, which links with the Seddinsee and provides a commercial waterway link between Berlin and Poland.The Langer See is crossed by two of Berlin's passenger ferries that are operated by the BVG, the municipal transport operator. The F12 crosses from Müggelbergallee (in Köpenick) to Wassersportallee (in Grünau), and operates all year. The F21 crosses from Krampenburg via Große Krampe (both in Müggelheim) to Zum Seeblick (in Schmöckwitz), and operates only in summer.The regatta course on the Langer See at Grünau was used for the Olympic canoeing and rowing events at the 1936 Summer Olympics.

The Müggelturm (“Müggel Tower”) is a popular day-trip destination in Köpenick, in southeastern Berlin, Germany. It is located to the south of the Müggelsee lake in the Müggelberg hills atop the Kleiner Müggelberg (“Small Müggelhill”). Berlin's highest natural elevation is the nearby Großer Müggelberg at 115 m.

The Seddinsee is a lake in the south-eastern outskirts of Berlin, the capital city of Germany. The lake is aligned south-west to north-east, with its south-western end adjacent to the Berlin suburb of Schmöckwitz. Here the Seddinsee meets the Zeuthener See and Langer See, two lakes that form part of the course of the River Dahme. The Seddinsee is navigable. It has a length of about 2.9 kilometres (1.8 mi) and a width between 500 and 1,000 metres (1,600 and 3,300 ft). Several little islands are in the lake. Besides its natural connection to the River Dahme, the Oder-Spree Canal enters the lake on its eastern shore, whilst the Gosen Canal links the lake's northern end to the Dämeritzsee. Besides seeing considerable sightseeing and leisure traffic, the lake also forms a link in several commercial navigation routes, including the route from Berlin to Poland via the River Dahme and the Oder-Spree Canal.

The Müggelsee (German pronunciation: [ˈmʏɡl̩ˌzeː] (listen)), also known as the Großer Müggelsee, is a natural lake in the eastern suburbs of Berlin, the capital city of Germany. It is the largest of the Berlin lakes by area, with an area of 7.4 square kilometres (2.9 sq mi), a length of 4.3 kilometres (2.7 mi) The lake is in the Berlin district of Treptow-Köpenick. The suburbs of Köpenick, Friedrichshagen, Rahnsdorf and a little section of Müggelheim border on the lake. The lake itself is 8 metres (26 ft) deep at its deepest point. At its south end are hills called the 'Müggelberge', which are 115 metres (377 ft) high; they were formed during the Pleistocene (as a kettle hole, remaining at Weichselian glaciation). On the so-called 'Kleiner Müggelberg', the much-visited and popular 'Müggelturm' (a tower) was built, the first one in 1889 (destroyed in a fire in 1958), and the current one in 1960/61. The tower offers extensive views over the lake and the forests against the Berlin skyline.The River Spree flows into the lake via the smaller Kleiner Müggelsee, which is only 0.16 square kilometres (0.062 sq mi) in area. The Friedrichshagen waterworks on the northern bank of the Müggelsee obtains most of its water from the lake. There are also numerous deep wells located near the banks, and are mainly fed by the bank filtrate and only to a small share by groundwater.

The Oder–Spree Canal (German: Oder-Spree-Kanal pronounced [ˌoːdɐˈʃpʁeː.kaˌnaːl] (listen)), is a canal in the east of Germany. It links the Dahme river, at Schmöckwitz in the south-eastern suburbs of Berlin, with the River Oder, at Eisenhüttenstadt. It provides an important commercial navigable connection between Berlin and the Oder, and hence Poland.The canal has several connections to the River Spree. For a stretch of about 20 kilometres (12 mi) near Fürstenwalde the canal utilises the river as part of its route, and there is a navigable connection to the river upstream of this section, although these reaches are relatively shallow and are generally only used by leisure craft. However the principal connection is via the River Dahme, which joins the River Spree at Köpenick, to the east of the centre of Berlin.

Schmöckwitz (pronounced [ˈʃmœkvɪts] (listen)) is a German locality (Ortsteil) within the Berlin borough (Bezirk) of Treptow-Köpenick. Until 2001 it was part of the former borough of Köpenick.

The Zeuthener See (German pronunciation ) is a lake situated to the south-east of Berlin, the capital city of Germany, in the states of Berlin and Brandenburg. At an elevation of 34 metres (112 ft), its surface area is 2.33 square kilometres (0.90 sq mi).

Zeuthen is a municipality in the district of Dahme-Spreewald in Brandenburg in Germany.

Eichwalde is a municipality of the Dahme-Spreewald district in Brandenburg, Germany, situated at the southeastern Berlin city limits. With 2.8 km² (1.1 sq mi) it is the smallest Brandenburg municipality by area, while its population density is the second highest (after Glienicke/Nordbahn).

Fredersdorfer Mühlenfließ is a river of Brandenburg and Berlin, Germany. It flows into the Müggelsee, which is drained by the Spree, near Rahnsdorf.
