The catalog “The Revealed River Wonders” presents in a unique and modern way the hidden beauty of life in our city Ljubljana. In the depths of the Ljubljanica, which flows quietly under the most famous Ljubljana landmark, the Tromostovje, the magic world of the microscopically small river diatoms of algae cohabits that Urška and Tomaž Draž captured into knitted loops. Printed catalogs are available at our Institute and in Otter shop.
