The Speicherstadt in Hamburg, is the largest warehouse district in the world where the buildings stand on timber-pile foundations, oak logs, in this particular case. It is located in the port of Hamburg—within the HafenCity quarter—and was built from 1883 to 1927. The district was built as a free zone to transfer goods without paying customs. As of 2009, both the district and the surrounding area are under redevelopment. As the first site in Hamburg, it was awarded the status of UNESCO World Heritage Site on 5 July 2015.
