Mizbayach - The large copper Mizbayach stood in the Azarah. Korbanos were slaughtered in the Azarah and burned on the Mizbayach. The top of the outer Mizbayach measured 28 Amos (about 55 feet) by 28 Amos. Three stacks of logs were arranged daily on the Mizbayach. Each one was called a Maarachah. The largest Maarachah was used for burning Korbanos. The second largest was used primarily to produce embers for the burning of Ketores. The function of the third Maarachah was to maintain a constant fire. On Yom Kippur a fourth Maarachah was added to produce embers for the burning of incense in the Kodesh Hakodoshim.
