The capital and surrounding region has a rich and lengthy industrial history according to Andris Biedriņš, Chairman of the Latvian Industrial Heritage Foundation.
"In an effort to save them from abandonment or demolition, there is a sizable number of production and transport objects listed as protected cultural heritage sites in the world. In Europe there is great interest in the history and industrial heritage of former factories and they are able to attract both domestic and foreign tourists. Also there are many different industrial heritage objects in Latvia, because during the 19th and 20th centuries this was one of the most industrially developed provinces of the Russian Empire, and Riga before the First World War was the third largest industrial city."
