of the city's main television tower. East of Winogrady, close to the river, is the neighbourhood of Szeląg, and north of this the housing estate of Wilczy Młyn. North of this is the Naramowice neighbourhood, and then Umultowo. West of Umultowo is the estate called Osiedle Różany Potok, named after Różany Potok or Strumień Różany ("Rose Stream") which flows eastwards towards the Warta, also giving its name to the small neighbourhood of Różany Młyn ("Rose Mill"). North of Umultowo are two small neighbourhoods called Nowa Wieś Górna and Nowa Wieś Dolna ("Upper New Village" and "Lower New Village"), and then Radojewo, which has a palace and park complex and nature reserve. The main road continues northwards from there towards Biedrusko, passing through the adjacent military area. Further west, north of Piątkowo, is a wide, mainly open area called Morasko (part of Poznań since 1987). The former village of Morasko itself is close to the city's northern boundary, and contains a palace used chiefly as a convent. West of this is a nature reserve around a series of supposed meteorite craters. This reserve also contains Poznań's highest point, the hill known as Góra Moraska, with an altitude of . The wider area of Morasko also includes the neighbourhood called Huby Moraskie, as well as the complex of buildings of Adam Mickiewicz University located just north-east of Piątkowo, used mainly for natural science teaching. Stare Miasto contains quite extensive areas of forest, including in the area between Piątkowo and Naramowice, along the river from Naramowice northwards, and in the area of the Morasko reserve. Poznań's fast tram line, Poznański Szybki Tramwaj (popularly known as Pestka), runs from west of the city centre, initially as an elevated line, and then in a cutting passing through Winogrady and Piątkowo to the terminus and bus station at Osiedle Sobieskiego on the northern edge of Piątkowo. There are also older tram lines serving the southern and eastern parts of Winogrady. The main railway line running east from Poznań passes through Stare Miasto, with a station called Poznań Garbary just south of the Cytadela. There is also a relief line passing through the district further north, used for freight transportation. History The Old Town neighbourhood – the medieval walled city – constituted the city of Poznań from its founding in 1253 until 1797, when (under Prussian rule) the city's borders were extended to take in areas to
