Jatka, Historic slaughterhouse and cultural monument in Moravská Ostrava, Czech Republic.

Jatka is the red brick slaughterhouse of Ostrava, located in central Moravská Ostrava and once serving as the city's main meat processing facility. The building displays typical early 20th-century industrial architecture with a straightforward, functional design built for its original purpose.

The city began building the slaughterhouse in 1881 at the corner of Stodolní and Porážková streets, on the site of the pork cattle market, to concentrate all commercial slaughtering under veterinary control. It was rebuilt in 1890–1891 and modernised again in 1902–1903 with a 20-metre brick cooling tower, then largely replaced in 1927–1928 by Walter Frese's complex. In 1951 it was nationalised, and in 1965 operations moved to a new plant in Martinov.

The site's name, Jatka, is simply the Czech word for slaughterhouse, still used for the PLATO Ostrava gallery that opened here. The 20-metre brick cooling tower of 1902–1903, with air cooling, a water reservoir and a moisture condenser inside, remains the landmark of the complex.

The complex stands at the corner of Stodolní and Porážková streets in central Moravská Ostrava. Since 2020 it has been converted into the PLATO Ostrava city gallery by the Polish studio KWK Promes, and it entered trial operation after inspection in May 2022, opening its doors until the first exhibition launched in September that year. Visitors should check the gallery's current opening before arriving.

The 20-metre brick tower of the cold-storage hall, built in 1902–1903 to Anton Möller's design, held air-cooling equipment, a water reservoir and a moisture condenser across its three floors. It was entered in the monument register in 1987, and the whole complex followed in 1994.
