Westwork
（重定向自Westwerk）
A westwork (German:Westwerk) is the monumental, west-facing entrance section of a Carolingian, Ottonian, or Romanesque church. The exterior consists of multiple stories between two towers. The interior includes an entrance vestibule, a chapel, and a series of galleries overlooking the nave. A westwork is usually broader than the width of the nave and aisles. It is sometimes used synonymously with narthex.
