A terraced wall, also a terrace wall, or a terraced retaining wall is a wall that is divided into sections (terraces) over a slope. Such designs are useful when building on a steep grade. Terraced walls may be built with many different materials.

Some craters have terraced walls, which includes complex craters.^[1][2]

Types of terraced walls

A partially terraced wall is designed so that the upper terrace and lower terrace come back together, forming a taller wall. The wall may still work well, but may have aesthetic issues.^[3]

There are two types. In an independent terraced wall, the upper wall applies little or no weight load on the lower wall. In a dependent terraced wall, the upper wall places a weight load on the lower wall.^[4]
