Northern Side Aisle
The foundations of the northern side aisle were found in the excavation of 1919 (Anjou, 1930, p. 28-29). Also the remnants of the entrance were found (Anjou, 1930, p. 40). The height of the walls were made the same than in the southern side aisle.
Southern Lateral Tower
The southern lateral tower is an interpretation by Welin of the L-wall that was found south of the crypt in the 60's (Welin 2012, p. 187-193).
Central Tower Narthex
The central tower of the narthex is based on an interpretation of Welin, who suggests that walls of the crypt that we see today contain parts of the original church (Welin 2012,p. 190). It was modelled following the outline of the crypt, but with thinner walls of 117cm. The closed portal that is situated today in the first floor above the crypt belongs to the original church according to Welin. It was used to determine the height of the rooms inside the central and lateral towers. Welin suggests that the central tower was either as high as the nave or higher. It was modelled higher because the central tower is slightly broader than the nave, which would make it more difficult to make a joint roof. For each floor the walls were made 20-25cm thinner to take into consideration the construction of the ceilings. On the third floor the walls reach a thickness of only 50cm and the walls were not made thinner at the height of the fourth floor.
Many researches believe that the well that is situated today in the north-western corner of the crypt belongs actually to the original church (Ericsson 2012, Nilsson 2012).
Northern Lateral Tower
No archaeological remains could be unearthed from the northern lateral tower. Welin assumes that the narthex had a southern and northern lateral tower of the same shape (Welin 2012, p. 190).
Windows Side Aisles and Chancel
No evidence is left of the original windows in the side aisles and the chancel. They were reconstructed according to style coherence with round arches and in the same size than the windows in the nave, with exception of the window in the eastern facade of the chancel which was modelled much larger.
The first and second floor of the central tower
There is no evidence of how the central room in the groundfloor of the narthex could have communicated with the nave and the lateral towers. However, Welin suggests that there were three arcades towards the nave and that the floor in the central room was at the same height than the floor in the crypt today(Welin 2012, p. 191). The steps towards the nave were modelled with the same dimensions than the original steps of the crypt of 20x20cm (Anjou 1930, p. 61). Welin also assumes that the first floor probably opened up towards the nave through galleries (Welin 2012, p. 191). He does not specify how the central room is connected to the lateral towers and thus they only received typical Romanesque large round arched portals.
The window beneath the portal and the entrance to the lateral towers
There is no evidence of a window beneath the portal on the first floor or the door in the southern lateral tower. However, Welin suggests that there the original church used to have a window where now the portal of the crypt is situated. Furthermore, he believes that the lateral towers most likely had entrances for themselves and where open towards the outside (Welin 2012, p. 190). The door was modelled at the center of the lateral tower, with the floor in the tower at the same height than the floor outside the church, which is about 50cm higher than the floor in the central room (according to Welin the same than in the crypt today). This is the reason why the arcade between the lateral tower and the central room, received steps to overcome this difference in the height of the groundfloor.
The uppermost floor in the central tower
There is no evidence of how the upper floors of the central towers looked like and how they were used. However, since romanesque towers often were also used as belltowers it was decided to model the uppermost floor of the central tower with sound openings.
Windows and doors
There is no evidence of the windows in the lateral and central tower or how the central tower and the lateral tower comunicated on the upper floors. Also Welin does not give any suggestions. Thus, windows and doors were modelled based only on style coherence and logic.
The height of the nave
The height of the nave is assumed to be 11,5m (Anjou, 1930; pp. 38-39).
