Between 1991 and 2008, the complex comprising the Galeria, the reception building, and the information and visitor center was constructed. Together, these structures form the impressive entrance to the Viessmann plant in Allendorf.

The Information Center, which was completed in 2008 and includes a heating plant, was designed to accommodate the growing number of customer training sessions and factory tours; in addition to a sales office, it features training and seminar rooms with communication areas.

Through the directly adjacent Galeria, built in 1993, and the “Via Temporis,” constructed in 2003, visitors gain insights into production and the company’s history. The spacious reception area opens onto a restaurant with an adjoining terrace. The heating plant is located in the two lower levels, and its striking chimneys are visible from afar.
