The present invention relates to a reinforced sandwich structure (10) comprising stacked in height direction thereof, at least one top layer (2) and at least one bottom layer (3) comprising a fibrous reinforcing material, which top and bottom layer sandwich between them at least one core (1) of a foamed material, the sandwich structure being impregnated with a resin material. The at least one core material comprises at least one insert (9) which extends in height direction of the reinforced sandwich structure (10) over at least part of the height thereof and in at least one of the longitudinal and transversal direction thereof. The at least one top layer (2), the at least one bottom layer (3) and the at least one core material which comprise the at least one insert are connected to each other by means of reinforcing fibers, at least part of which extend in height direction of the sandwich structure.
