Wasserpark Frankfurt, Urban park in Nordend, Frankfurt, Germany

Wasserpark Frankfurt is a public park of just under 3.7 hectares in the Nordend district, bordering Bornheim, between Friedberger Landstraße and Dortelweiler Straße. Its hill covers an underground reservoir 132 by 67 metres and 4.10 metres high, built of red Main sandstone. Above ground stand several pump houses and a small domed central building in Neo-Renaissance style modelled on Aschaffenburg Palace, with wrought-iron gates bearing gilded door-knob rosettes and lion heads holding rings.

The facility was built in 1873 as Frankfurt's first long-distance water pipeline, bringing fresh water from the Vogelsberg mountains to the growing city. This infrastructure was crucial in allowing the population to expand and the city to develop into a modern metropolis.

The park's name comes from the waterworks that opened here in 1873, when Vogelsberg spring water first reached the reservoir. A nine-station water trail explains the cycle from spring to tap, and since 1880 the Frankfurter Imkerverein has kept a bee garden here, selling honey in the park on Sunday afternoons.

The park is well connected by public transport and easy to reach on foot, since the grounds are relatively flat and clearly marked. Most visitors can explore the entire area in about one to two hours without any special equipment or preparation needed.

Beneath the park's hill are four underground water chambers that can store about 25,000 cubic meters of water. These hidden reservoirs remain active today and supply Frankfurt's drinking water network, yet visitors walking above them cannot see them.
