FRONX – Essen Frohnhausen doesn’t necessarily have a reputation for being particularly worth seeing. So, with a twinkle in the eyes, it sometimes is titled as Fronx. Undeserved and au contraire! Frohnhausen is Essen’s art nouveau neighbourhood. Please find below what I have found today in Frohnhausen, at a wall whose expiration date is about to expire in the near future. Until then a playground for people of all stripes.
