Familoks were built at the end of the 19th century and beginning of the 20th century, in the cities and towns of Upper Silesia. They are present in almost every sizeable Silesian city.

Today, they are often run-down and in crime-ridden neighborhoods. They were often built in complexes, resulting in "familok districts" in cities today. Some districts even had their own church and communal yards, acting as "cities within cities".
