A trough is usually a long, narrow, open stone container, usually box-like and most often used to feed or water animals. Troughs can be square, round, or D-shaped. Larger D-shaped troughs were used in villages with a pump for water. The word "troh" is an old English or Saxon word similar to "trog", which is old Norse for trough. Although most often carved out of a single block of stone some troughs were made from squares or "flags" of local stone that was divided. Many troughs have tethering holes so that animals could be tied to them.
Stone troughs were hewn or carved from sandstone, limestone, granite, or even marble, usually a local stone. Troughs make a wonderful garden planter, can be used as a fountain or water feature, or simply as a naturalistic focal point in the garden. Uniquely carved no two troughs are ever the same.
