Hatfield House is of vast extent; it is of brick, with stone dressings. It was built between the years 1605 and 1611, by Robert Cecil, first Earl of Salisbury. After being suffered to fall into decay, it was restored and beautified by the sixth earl, about the middle of the last century. In 1835, a great part of the west wing was destroyed by fire, little being left of that part of the house besides the outer walls. On this mischief occurring, occasion was taken to effect a general reparation, which was brought to a close last year (1846). The house is in the form of an half H, comprising a centre and two wings, the hollow part being towards the south. The centre is a magnificent example of the Palladian style, and, although of mixed architecture, presents, in its totality, a design of great richness and beauty. The basement-story contains an arcade, with eight arches, divided externally by pilasters, whereof the upper parts are fluted, and the lower parts enriched with Elizabethan arabesques. The lower pilasters are Doric, the upper Ionic. The wings are massive, and comparatively plain, supported at each corner by square turrets, seventy feet high to the gilded vanes; the space between, comprising three stories, is relieved by a fine oriel window, of two stories. The centre tower, over the grand entrance, is also seventy feet high; it has three stories, with coupled columns at the corners, the whole having an agreeable pyramidal effect. The third story of the tower contains a clock, and also the armorial bearings of the founder, with the date 1611, in which year the present house was finished. The length of the southern front is 300 feet, the centre being 140 feet, and each wing 80 feet wide, with a projection from the centre of 100 feet. [Illustration] The northern front is plain--a severe simplicity, nearly allied to grandeur, being its chief characteristic; the centre compartment, with its entrance-doorway below and noble clock-tower above, being the only elaboration it contains. Of this front we give a view, as seen from the avenue of trees which marks the approach on this side.
