Rolf Engelen is a Dutch visual artist who was born in 1963. He works mainly in the public space - both on a project basis and on assignment - and is involved in several collaborations that take place in the field of social sculpture and language. He also makes autonomous work. He is co-founder of Museum Van Nagsael and founder of the Tweedekansplant company, which has been saving plants from the streets since 1997. Engelen often involves the audience in his work. The gift plays an important role in this.
