Modular model of a cathedral. A bay section, the transept, the apse, the facade, and the flying buttresses are included as separate models, along with a tower and optional spire. Also included are complete sides of the cathedral, with a transept and several bays either side, to save time putting it together. (You can always make this longer by adding extra bays). Mainly done for the interior, where most of the detailed modelling is to be found, but the outside is quite presentable if a bit on the minimalistic side for a gothic cathedral.
