Cruciform Plan

This is a common description of Christian churches. In Early Christian, Byzantine and other Eastern Orthodox forms of church architecture this is more likely to mean a tetraconch plan, a Greek cross, with arms of equal length or, later, a cross-in-square plan, more like a square. In the Western churches it usually, though not exclusively, means a church built with the layout developed in Gothic architecture comprising:

• An east end, containing an altar and often with an elaborate, decorated window, through which light will shine in the early part of the day.
• A west end, which sometimes contains a baptismal font, being a large decorated bowl, in which water can be firstly, blessed (dedicated to the use and purposes of God) and then placed upon infant or older believers as a sign of their dedication.
• North and south transepts, being "arms" of the cross and often containing rooms for gathering, small side chapels, or in many cases other necessities such as an organ and toilets.

In churches that are not oriented with the altar at the geographical east end, it is usual to refer to the altar end as "liturgical east" and so forth.

Cruciform Sword

The plain sword used by knights, distinctive due to the flat bar used as a guard. The overall shape of the sword when held point down is that of a cross. It is believed this shape was encouraged by the church to remind Knights of their religion. It was however very popular due to the protection it offered to the hand and certain attacks that rely on the cross to trap the blade of the enemy. See sword.

The Cruciform

In the episode "The Sound of Drums" of the British science fiction television series Doctor Who, an object or location called "the Cruciform" is mentioned, as having been captured from the Time Lords by the Dalek Emperor. It is presumed to be something of great importance, since the Master considered losing it tantamount to defeat in the Time War, but no specific information other than that name has been given.
