An altarpiece is a work of art, often a painted or sculpted piece, that is placed behind an altar in a church. It serves both decorative and devotional purposes, enhancing the spiritual atmosphere of the space. Altarpieces can vary in size and complexity, ranging from simple panels to elaborate multi-part structures. Typically, altarpieces depict religious themes, including scenes from the life of Jesus Christ, Mary, or various saints. They are often created using materials like wood, canvas, or stone, and can be found in many styles, such as Renaissance or Baroque, reflecting the artistic trends of their time.
