On May 31 and June 1, 2025, the Museum Koenig Bonn opened its doors, cabinets, chests, and museum park to young and old, as it does every year. The festival of Bonn's five major museums on the Museum Mile featured live music from the stage, researchers offered insights into their work and behind-the-scenes access, and a variety of activities provided entertainment for children. Vegetarian delicacies from several food trucks rounded out the offerings.
Despite some difficult weather conditions, a record number of visitors came to Museum Koenig during the 2025 Museum Mile Festival. Although the park had to be evacuated for almost two hours on Saturday afternoon due to severe weather, the museum was packed during this time, and the resulting program changes were met with understanding from visitors. A pleasingly high number of guests stayed at the Museum and its park until the evening.
The museum park offered many hands-on activities on both days: The FÖRTAX project, for example, delighted visitors with its activities promoting greater biodiversity and nature conservation. FlowerPowerBalls (seed balls containing native plant seeds) were handcrafted with great enthusiasm, especially by younger guests, and are intended to promote insect diversity and make our environment a little greener.
This year, the Museum Mile Festival also marked the kickoff of the "Summer of Change," a cultural festival in which many Bonn institutions, including the Museum Koenig, are participating. The "Summer of Change" theme is "ecological sustainability." Fittingly, the Bonn Repair Cafés were present at the Museum Mile Festival in the park, offering repair services and assistance. Birdhouses could also be made there, and there was a sustainability rally for children. With the support of Bonn Orange, the local waste disposal company, guests of the Museum Mile Festival were also able to equip themselves with gloves, garbage bags, and a map and collect garbage on their way to the other museums along the Museum Mile.
There were many prizes to be won at the Wheel of Fortune and the Alexander Koenig Society raffle at the Museum Koenig. At the booth of the German Society for Herpetology and Terrarium Science, visitors could learn about animal husbandry, conservation breeding, and the endangered status of reptiles and amphibians.
The musical program was also particularly popular with guests of the Museum Mile Festival: On Saturday evening, the audience in the park listened to soul and funk sounds from the band Plenty Fourty and rock and pop from Crowns of Recreation. On Sunday, the ensemble hier&jazz and the orchestra Camerata Nonnenwerth & Friends performed.
