Riehler Heimstätten, Retirement community in Riehl, Germany.

Riehler Heimstätten is a senior and disability housing complex in Riehl, Cologne, built from 1927 on the site of the former Pioneer Barracks. Its buildings, including a residential foundation with nine houses, a care home and a support area, are arranged around a large tree-lined meadow that was once the parade ground. The grounds cover 25 hectares and extend from Boltensternstraße to the Rhine meadows.

The complex was founded in 1927 on the grounds of former military barracks and grew rapidly into one of Germany's largest such facilities. The project expanded significantly within a few years and shaped how people thought about senior living.

The name Riehler Heimstätten refers to the former Pionierkasernen site on Boltensternstraße, converted from 1927 into a "Altenstadt" on the initiative of Hertha Kraus, head of Cologne's welfare office. A central music square for open-air concerts was inaugurated on 26 June 1932, and a prayer room for Protestant residents was set up in March 1929 in the former infantry regimental canteen.

The grounds cover 25 hectares between Boltensternstraße and the Rhine meadows, with the former parade ground kept as a large tree-ringed lawn. The complex is a care home, not a visitor attraction, so access is limited to residents, their guests and staff. The site was raised about two metres with Rhine gravel to guard against flooding.

The site's 25-hectare grounds were raised about two metres with Rhine gravel before the barracks were built, to guard against the river's frequent floods. The former parade ground became a large tree-ringed meadow, and a central music square for open-air concerts opened on 26 June 1932.
