As you approach the front of the church you will come to a step leading to
the Chancel The Chancel is where the clergy (the priests) and the choir
sit.

当你走向教堂前方，拾阶而上，便来到Chancel(高台)，神职人员(神父)和唱诗班所
在之地。

(The Church of St. Andrew)

In Protestant churches the chancel is the space around the altar at the
east end, often enclosed, for use by the clergy.

在新教的教堂中，高台是位于东侧环绕祭坛的一块地方，通常是围起来的，为神职
人员所用。
