The invention relates to a door comprising a door leaf (10) which can be moved between an open position and a closed position and a guide arrangement for guiding the movement of the door leaf along a predefined path between the open position in the closed position, wherein the guide arrangement has at least one guide web (100) which is arranged fixedly with respect to a wall opening, extends at least along a portion of the predetermined path, and has two outer boundary surfaces (102, 104) and at least two guide devices (32, 34) which are fastened to the door leaf (10), wherein a first outer boundary surface (102) of the guide web (100) forms a surface for a first guide device (32) and the second outer boundary surface (104) of the guide web (100) forms a second guide surface (104) for a second guide device (34). Magnetic devices (1000, 1010, 1100) can be arranged on the door leaf and on the guide bar for guiding in a contactless manner.
