Postgalerie, which ERWE Retail Immobilien GmbH had already acquired in May 2017, is located at the beginning of the pedestrian zone in Speyer's city center, which extends to the famous Speyer Cathedral. The historic building at Postplatz 1 in Speyer currently has around 8,300 sqm of retail and restaurant space as well as around 8,750 sqm of hotel, office and warehouse areas. A conceptual change of the user mix will expand the center's total lettable space to more than 17,000 sqm. The revitalization of the entire gallery includes the refurbishment of the retail space as well as the mall of  Postgalerie in a bright and modern design. Furthermore, the share of gastronomy space will be increased to improve the quality of the stay and to attract more visitors to the gallery.

A major focus of the conceptual change is the conversion of previously vacant office space into hotel space. A lease agreement for the new space was signed with the Amedia hotel group in June 2018. Amedia now operates a 4-star hotel with 111 rooms at the Postgalerie.

In January 2021, the remaining hotel rooms and the restaurant space were handed over to the Amedia Hotel Group. In June 2022, a space on the first floor was let to an eye clinic. The clinic is to become the nucleus for a new health concept for the Postgalerie, in the context of which the letting of further individual spaces to medical practices and related institutions is planned. The occupancy rate of the building stood at 74 percent in June 2023. All project-related costs remain within budget.

Moreover, further modernization measures were initiated in 2022. An outdoor advertisement concept has been prepared, observing the requirements of the historic preservation authority. Lastly, the modernization measures include a contemporary lighting concept, a landing and a staircase in the access area.
