Memorial Pillbox Flakturm Esterházypark

On 24 September 2020, a memorial plaque was unveiled in the Esterházypark. The "Panel for the Contextualization of the Flakturm in the Esterházypark" commemorates the history of the Flakturm, which has housed the House of the Sea since the 1950s. The plaque was erected as part of the park's redesign. The initiative came from the Mariahilf District Office, and the project was funded and implemented by KÖR Wien. The panel provides comprehensive information on the architecture and history of the Flakturm on both sides; the text is presented in German and English.
