The corner building of the Inka Disabled People’s Trading Cooperative, constructed between 1964 and 1970, housed offices and warehouses, a beer hall, and the INKA student café (Intellectual and Scientific Academic Club) until 1991. In 1999, the building underwent a complete renovation, taking on the shape of an inverted “metal pear,” intended by its designers (Katarzyna Boguszewska, Marek, and Maciej Powązka) to “clearly accentuate the corner of the street block” and provide it with a “dynamic contrast.” The result was the seven-story INKA Department Store (including a basement, lower ground floor, and attic with a terrace), which remains highly controversial in Olsztyn to this day. In 2024, the Inka company put the building up for sale for PLN 6.5 million. Address: Feliksa Nowowiejskiego 1, Olsztyn.
