Recent results on gropes and their fundamental groups are presented. Gropes are an important construction in geometric and algebraic topology, introduced by \v Stańko and Cannon.
Open infinite gropes are nice 2-dimensional CW complexes and Eilenberg-MacLane spaces of their fundamental groups, but they are on the one hand closely related to wild spaces
and on the other hand their fundamental groups are in some sense wild.
