Aisles in Architecture
- In architecture, an aisle is a wing of a house or a lateral division of a large building.
- The earliest examples of aisles can be found in the Basilica Ulpia in Rome.
- In Gothic architecture, the roofs of the aisles are lower than the nave, allowing light to enter through clerestory windows.
- In Romanesque architecture, the roofs of the aisles are at roughly equal heights to the nave.
- Some churches in Germany have aisles and nave roofs at the same height, known as Hallenkirchen.
- Aisles in churches are passageways separated from the nave by colonnades or arcades.
- Aisles can be categorized as nave-aisles, transept-aisles, and choir-aisles.
- In Gothic architecture, the aisles' roofs are lower than the nave's roof.
- In Romanesque architecture, the roofs of the aisles are slightly lower than the nave's roof.
- Some churches, like St. Peter's Basilica in Rome, have multiple aisles on each side of the nave.

- Inspectors impose fines for blocking or restricting passage in aisles.
- Insurance companies have safety inspectors to ensure compliance with aisle requirements.
- The Americans with Disabilities Act sets standards for building access, including aisle width for wheelchair access.
