Medieval builders almost always started building a church at the east end of the chancel, the place that housed the high altar, the necessary prerequisite for worship. Consequently this is often the oldest part of a remaining medieval church. However, rebuilding in a more modern style, or expansion of the church, often meant building anew, and in such cases the area around the high altar may not be the oldest. Sometimes a font, the necessary prerequisite for admission to the faith, is the oldest part of the church. And, many churches kept a venerated old font even when rebuilding took place. But a font, though usually made of stone, is easily moved, and many were replaced, or even moved elsewhere. The font stem at Tewkesbury Abbey (above) has ballflower decoration that dates it to the fourteenth century (the bowl is newer), similar to the age of the chancel, but a couple of hundred years more recent than the nave.
