Petersberg, Halle
The Petersberg, at , is the highest point in the district of Saalekreis in the German state of Saxony-Anhalt. Its name is derived from St. Peter's Church, which is on the hill. Until the 14th century the Petersberg was known as the Lauterberg. Geography. The Petersberg is located about 10 kilometres north of the German city of Halle on the River Saale not quite halfway between Halle and Köthen. The municipality of Petersberg with its hamlets of Drehlitz and Frößnitz lie on the hill. At the foot of the hill are the villages of Ostrau and Wallwitz  as well as three small nature reserves. On the southern slopes of the hill is a small lake. A stretch of the A 14 motorway runs past the Petersberg to the west and south, and the B 6 federal highway runs by to the southwest. They form a junction at "Halle-Trotha", from where the Petersberg may easily be reached. Geology. The Petersberg is the highest point of the Halle Porphyry complex. It was formed, like the other porphyritic domes in the surrounding area, during the Upper Carboniferous and Lower Permian by the solidification of numerous molten lava flows under  the earth. In the slowly cooling lava, easily visible feldspar and quartz crystals were formed. The Petersberg consists of small-grained Halle porphyry – this hard rock is used mainly as a raw material for the manufacture of ballast and gravel. The present shape of the hill is a result of the last ice age. The surrounding loose rock was cleared away by the ice sheet leaving the hard porphyritic core behind. The top of the hill stood clear of the glacier as a nunatak. Petersberg Abbey. Petersberg Abbey with its collegiate church of St. Peter is a former Augustinian monastery . Since 1999 it has been used by an Evangelical monastic community of the Community of the Christ-Brotherhood Selbitz. Bismarck tower. One of the 15 surviving Bismarck towers in Saxony-Anhalt stands on the Petersberg. Its 15-metre-high tower was built to a design by Wilhelm Kreis and inaugurated on 24 September 1902. The observation tower that was badly damaged in the Second World War was thoroughly renovated in 1999/2000, so that it is once again climbable for the first time since the war. Communication towers. There is a communication tower on the Petersberg at which was built in  1963 and became operational on 1 May 1965.
