This former rice-husking plant became a concentration camp in 1943 and has been a national monument and museum since the 1960s.
The site commemorates the 5000 people who perished here and the many thousands more who passed through on the way to Nazi forced labour and death camps. These included a great many of the city's Jewish population along with Triestine and Slovenian resistance fighters.
Although the death cells remain, most of the camp's horrific wartime structures were destroyed by the retreating German forces in 1945. The monument solemnly traces their outlines in metal and stone, their absence creating areas of reflection. A collection of prisoners' photographs, letters and other artefacts are deeply personal and vividly alive.
Take bus 8 from the train station, or bus 10 from the Riva, a 20-minute trip; from the last bus stop walk past the stadium, turning left into Via Palatucci.
