ALatin cross orcrux immissa is a type ofChristian cross in which the vertical beam sticks above thecrossbeam,[1] giving the cross four arms. Typically the two horizontal and upper vertical arm are the same length, although sometimes the vertical is shorter, however the lower vertical arm is always much longer than any other arm.[2]
When displayedupside down it is calledSt. Peter's Cross, because he wasexecuted on this type of cross.[3] When displayed sideways it is calledSt. Philip's cross for the same reason.[3]
Many churches of different time periods are designed using the Latin cross plan. When looked at from above, it takes the shape of a Latin cross. A Latin cross plan primarily contains a nave, transept, apse, and narthex.

The Latin cross is present in archeological findings predating Christianity by several millennia. In pagan Rome it was represented in military standards of Roman legions.

Nowadays the Latin cross is mostly used to represent all ofChristianity andChristendom, given that it teaches thatJesus sacrificed himself for humanity upon it, atoning for the sins of the world.[4][5] It is especially used among the denominations ofWestern Christianity, including the Roman Catholic tradition and several Protestant traditions, such as Lutheranism, Moravianism, Anglicanism, Methodism, and Reformed Christianity, as well as by Anabaptists, Baptists, and Pentecostals.[6] In certain periods, such as during the 16th centuryEnglish Reformation of the Anglican Church, the Latin cross was disfavored by a minority of theologians such asNicholas Ridley, though in the overall history of the Western Christian Churches, this was short-lived.[7]

A Latin cross plan is afloor plan found in many Christianchurches andcathedrals.[8] When looked at from above or inplan view it takes the shape of a Latin cross (crux immissa).[9] Suchcruciform churches were very common in theWest during theRomanesque period.[2] The ideal church plan tended to be symmetrical around a central point during theRenaissance.[10] The longer arm of the Latin cross plan is thenave, which runs on an east–west axis and traditionally containsaisles orchapels.[10][11] Thetransept crosses the nave, running north–south, and can be the same width as the nave, or extend further on both sides to create a more pronounced cross shape. The east end is theapse, which traditionally contains the choir,chancel, or presbytery.[11] Many also have anarthex at the entry.[9]
