or the Nanotechnology Center. A stream called Konporta flows down along the eastern side of the area, but it was canalized under the ground almost all along to its mouth on the bay pushed by urban building pressure. Loiola It lies by the Urumea at the south-east end of the city. It comprises a small patch of detached houses (Ciudad Jardín) and a core area of 6-odd floor buildings. The district has recently gone through a major makeover, with works finishing in 2008. The road axis coming from important industrial areas (Astigarraga-Hernani) crosses the district heading downtown. A military base stands across the river, home to an uprising in 1936. Attempts by the city council to close it have been unsuccessful so far. Riberas de Loiola New modern district erected in the 2000s next to the city's inner bypass and south road entrance to San Sebastián. A pedestrian bridge spans the Urumea river onto the Cristina Enea Park. Martutene The Martutene district bordering to the south on the town of Astigarraga comes next to Loiola in the south direction. This part of the city features an industrial area, a football pitch for lower leagues, a disused vocational training building and enclosure as well as a prison, much in decay and due to be transferred soon to a new location, probably in the municipality's exclave of Zubieta, while this option is coming in for much opposition. Ulia This part stands on the east side of the city at the foot of the Mount Ulia Park, on the left hand side of the road heading from San Sebastián to Pasaia and Irun. It consists of a residential area, besides holding a number of educational institutions, culture and sports centres built since 1980. The Park of Nurseries of Ulia sits at the base of the road leading to Mount Ulia, with its name deriving from its function as a nursery of plants for the public gardens of San Sebastián throughout the 20th century until 2008. It includes two ancient water-tanks, architectonic elements, and specific flora and fauna. Añorga Former area of caserios on the outskirts of San Sebastián, the establishment in 1900 of the Cementos Rezola company in the neighborhood transformed Añorga into an industrial-type neighborhood, although it will lose its rural character that it once had. Even considering Añorga a single neighborhood, three distinct neighborhoods are generally distinguished: Añorga (Añorga Haundi), Añorga-Txiki
