Church treasury

A church treasury or church treasure is the collection of historical art treasures belonging to a church, usually a cathedral or monastery (monastery treasure). Such "treasure" is usually held and displayed in the church's treasury or in a diocesan museum. Historically the highlight of church treasures was often a collection of reliquaries.

As a result of gifts and the desire to acquire sacred artifacts, many churches over the centuries gathered valuable and historic collections of altar plates, illuminated manuscripts of liturgical or religious books, as well as vestments, and other works of art or items of historical interest. Despite iconoclasm, secularism, looting, fire, the enforced sale of treasure in times of financial difficulty, theft and other losses, much of this treasure has survived or has even been repurchased. Many large churches have been displaying their riches to visitors in some form for centuries.
