The architecture of the house is interesting. The doorway on the east is the true entrance door, showing Corinthian columns, while the Georgian porch at the west, supporting Ionic columns, is also considered a fine bit of architecture. There can be but little doubt that a house showing the dignity of exterior of the Royall house must have equally good interior woodwork. One realizes before opening the colonial door that he will see inside a fine old staircase, richly carved newel-post and balusters. The carving in this house as well as others of its type is not confined to the capitals that adorn its architraves. [Illustration: PLATE LXXX.--Hallway from the Rear, Royall House.] The long hallway extends the entire length of the house, with doors at either end. The stairway is on the eastern side facing the entrance, and is approached through an arch showing fine hand-carving. The balusters are carved in three different designs, while the newel-post is a combination of the three, one carved within the other. The staircase leads by low treads to the second-story floor. It is made under the old stair-builders' rule: "Twice the rise plus the tread equals twenty-five, Then cut on the string." There is no stucco work either in the hallway or in any other part of the house, and the wood throughout is pine. At the right of the hallway are double parlors, the western one being finished in wood which shows wonderful hand-carving done in 1732, and is lighted by arched windows. The outside shutters remain just as they were all through the lower part of the house when remodelled. The fireplace is finished in old Mulberry Dutch tiles and contains Hessian andirons, which differ from those generally seen in that they face each other. These andirons came into vogue just after the Revolution and were used to support backlogs. The eastern parlor is reached through folding-doors, which mask the original walls of the Winthrop House. These rooms, during the Royalls' reign, were used for many social events. The old wing arm-chair with Dutch legs came in about 1750. The silk-embroidered, Chippendale fire-screen shows beautiful, mythological pictures, while the old, steeple-topped brass andirons display to advantage the Mulberry tiles of 1847 and also the quaint old fireback. On the wall hangs a picture of Isaac Royall, who gave money to Harvard College to found the Royall Professorship of Law which was the foundation of the Harvard Law School.
