Using a micro-level dataset of over 5 million listings, house price indexes for Poland over the period 1996 to 2021 was constructed. The offer data for the biggest cities comes from two different sources. The earlier data were obtained from archival advertisements in photocopies, photographs or periodicals, then digitally reproduced and arranged in a database. The data from 2009 were collected from advertising portals (gratka.pl / otodom.pl)  several times a quarter. The hedonic indices were determined for each city and then aggregated. The constructed index has some limitations but provides information on the housing market in Poland for much longer than officially published.
