The castle has been developed into three “Wards,” as shown here in this Wikipedia aerial photograph of the castle.
The Lower Ward lies below and to the west of the Middle Ward and the Round Tower, entered through the Norman Gate between the two Wards; Henry the VIII Gateway is at the lower south side of this Ward.
Originally of medieval design, most of the Lower Ward was renovated or reconstructed during the mid-Victorian period to form a consistent Gothic form. At the west end of the Lower Ward is the Horseshoe Cloister, originally built in 1480, near to the chapel to house its clergy. It houses the vicars-choral, or lay clerks of the chapel. This curved brick and timber building (visible on the far left side of the aerial photograph above) is said to have been designed to resemble the shape of one of the badges of Edward IV.
On the north side of the Lower Ward is St. George’s Chapel and most of the buildings associated with the Order of the Garter. This huge building is the spiritual home of the Order of the Knights of the Garter and dates from the late 15th and early 16th century.
