Fort Diemerdam is part of the 'Stelling of Amsterdam'. This historical defence line was recently put on the UNESCO world heritage list. This ignited a re-development plan for Fort Diemerdam to make it accessible to visitors, tourists and those interested. The existing bunkers and fortress guardian house have been restored. The original plan of slopes and strongholds is restored and a nature conservation program has started. Emma architects has designed a new pavilion in which and from which Puur Produkties revives the fortress again with events, tours and catering.
