Amarantgasse (Oberlaa, “Heimkehrersiedlung”), named in 1957 after the plant genus Amaranthus from the foxtail family (Amaranthaceae). Amaranth is one of the oldest useful plants of mankind. Above all, the seeds of the grains reminiscent of millet are used. The food industry today uses amaranth in baby and children’s food, as an additive in bread, pastries and muesli, in pancakes and pasta, also in sausage products and in bars and snacks in the fast-food sector. The alley was previously called Randgasse.

Below the Amarantgasse runs the Laaerberg collecting sewer, which is intended to drain 278 hectares of the Laaer Berg. With a length of 1158 meters, it currently extends to the Ostbahn, which it will later run under, like the Aspangbahn. It was built in 1937, 1952 and 1955 with the concrete profiles 1.10/1.65, 1.00/1.50 and 0.90/1.35 meters, its gradient is 10, 17 and 18 ‰, its average depth 5.50 to 7.00 meters.
