In the same beauty of simplicity as the DC Open booklet, the DC Open App is an art guide for easy-to-use orientation during DC Open from September 4 to September 6. Providing information about the exhibitions in galleries, museums, instituttions and off-spaces as well as images, texts and customizable maps, the DC Open App puts the simple discovery of Cologne/Düsseldorf’s art scene in your pocket! DC Open stands for Düsseldorf Cologne Open Galleries, a joint opening weekend in both cities, celebrating the tenth anniversary of its founding this year. From September 4 to September 6, fifty-five galleries will show the year’s exhibition highlights. With the start of the art season in the fall 2026 — jointly organized by galleries from Düsseldorf and Cologne — the Rheinland will again become the center for current art events. DC Open is both a weekend for art-lovers as well as an international meeting point for professional art makers. After ten years, the DC Open shows that the Rheinland is stronger than ever: galleries, the traditional, liberal community of art collectors, the diversity and number of major museums and institutions, and lively off-spaces all contribute to the acclaim of this art region.

Verdict
