Vault

• A masonry roof or ceiling constructed on the arch principle.
• A barrel or tunnel vault, semicylindrical in cross section, is in effect a deep arch or an uninterrupted series of arches, one behind the other, over an oblong space.
In a cross-barrel vault, the main barrel (tunnel) vault is intersected at right angles with other barrel (tunnel) vaults at regular intervals.
• A quadrant vault is a half-barrel (tunnel) vault.
• A sexpartile vault is a rib vault with six panels.
• A fan vault is a development of lierne vaulting characteristic of English Perpendicular Gothic, in which radiating ribs form a fan-like pattern.
• A cross vault (or groin) is formed at the point at which two barrel (tunnel) vaults intersect at right angles. In a ribbed vault, there is a framework of ribs or arches under the intersections of the vaulting sections.

Victorian

The Victorian period saw a great change in town centres spurred on by the building laws introduced between 1848 and 1890. These tackled the problems of drainage, waste and water supply. With more powers and responsibility given to local councils the council house system was defined and provided housing for the vast majority of the population. It is from this period that we get the two-up and two-down terraced houses that have survived so well until today.
