In the context of this artwork, explain the Dismantling and current locations of the History.
The altarpiece remained in place until 1771, when it was dismantled in order to distribute the pieces between two altars. The 5-metre-high (16 ft) construction was dismantled and sawn up, and the paintings damaged in the process. Partial restoration took place in 1956. The dismantling also led to pieces going astray, either being sold or simply unaccounted for. Extant remains of the altarpiece not at Siena are divided among several other museums in Europe and the United States.
The panels in Siena are housed in the Duomo museum adjacent to the Duomo di Siena. The central panel, lower panels, and rear are displayed separately in the same room.
