17. A method to produce a foundation, comprising:
providing on-shore a formwork, wherein the formwork has an annular gap from a first, upper end towards a second, lower end which remains constant;
casting the formwork with a liquid mineral building material;
curing the concrete such that the cured concrete mineral building material forms a tower-shaped foundation structure; and
securing at least one binding element to the cured tower-shaped foundation structure;
wherein the tower-shaped foundation structure has a circumferential foundation wall extending in a longitudinal direction, the circumferential foundation wall being bounded on an underside by an underside end face and the circumferential foundation wall formed of the mineral building material;
wherein the at least one binding element is formed of a metallic material and arranged on the underside end face;
wherein a length of the at least one binding element from the underside end face to a lower end of the at least one binding element is at least 0.5 m;
wherein the at least one binding element comprises a longitudinally extending circumferential tie-in wall which extends from the circumferential foundation wall;
wherein the foundation is an offshore wind power structure foundation; and
wherein the foundation is configured to be rammed and/or vibrated into a seabed.
