The most striking structure of the upper court level is the so-called Rectangular Tower (45 metres). Like most of the court buildings, it mostly serves a decorative purpose as part of the ensemble. Its viewing platform provides a vast view over the Alpine foothills to the north. The northern end of the upper courtyard is defined by the so-called Knights' House. The three-storey building is connected to the Rectangular Tower and the Gatehouse by means of a continuous gallery fashioned with a blind arcade. From the point of view of castle romanticism the Knights' House was the abode of a stronghold's menfolk; at Neuschwanstein, estate and service rooms were envisioned here. The Bower, which complements the Knights' House as the "ladies' house" but was never used as such, defines the south side of the courtyard. Both structures together form the motif of the Antwerp Castle featuring in the first act of Lohengrin. Embedded in the pavement is the floor plan of the planned palace chapel.
The western end of the courtyard is delimited by the Palas (hall). It constitutes the real main and residential building of the castle and contains the king's stateroom and the servants' rooms. The Palas is a colossal five-story structure in the shape of two huge cuboids that are connected in a flat angle and covered by two adjacent high gable roofs. The building's shape follows the course of the ridge. In its angles there are two stair towers, the northern one surmounting the palace roof by several storeys with its height of 65 metres. With their polymorphic roofs, both towers are reminiscent of the Ch�teau de Pierrefonds. The western Palas front supports a two-storey balcony with view on the Alpsee, while northwards a low chair tower and the conservatory protract from the main structure. The entire Palas is spangled with numerous decorative chimneys and ornamental turrets, the court front with colourful frescos. The court-side gable is crowned with a copper lion, the western
