Ashlar

• (architecture)

In architecture, ashlar refers to a type of masonry construction that uses carefully cut and polished stones that are laid in regular courses to create a smooth, flat, and uniform wall surface. Ashlar masonry has been used in architectural construction for centuries, and can be found in a wide variety of building styles and periods.

Ashlar masonry is often used to create the exterior facades of buildings, as well as for interior walls, fireplaces, and other decorative features. The stones used in ashlar construction are typically rectangular or square in shape, and are laid in a pattern that creates a strong and stable wall.

There are several different types of ashlar masonry, including coursed ashlar, where the stones are laid in uniform courses of equal height, and random ashlar, where the stones are laid in irregular courses of varying sizes and shapes. In addition, ashlar masonry can be finished in a variety of ways, such as with a smooth, polished surface or a rough, textured surface.

Ashlar masonry requires a high level of skill and craftsmanship to execute, as the stones must be carefully selected, cut, and fitted together to create a precise and uniform pattern. However, when done correctly, ashlar masonry can create a beautiful and durable building that is both functional and aesthetically pleasing.
