Previous to entering upon an architectural description of the superb buildings recently erected in the vicinity of Regency Park, I shall confine myself at present to that object that first arrests the attention at the entrance, which is the church; it has been erected under the commissioners for building new churches. The architect is J. Soane, Esq. There is a pleasing originality in this gentleman's productions; the result of extensive research among the architectural beauties of the ancients, together with a peculiar happy mode of distributing his lights and shadows; producing in the greatest degree picturesque effect: these are peculiarities essentially his own, and forming in no part a copy of the works of any other architect in the present day. The church in question by no means detracts from his merit in these particulars. The principal front consists of a portico of four columns of the Ionic order, approached by a small flight of steps; on each side is a long window, divided into two heights by a stone transum (panelled). Under the lower window is a raised panel also; and in the flank of the building the plinth is furnished with openings; each of the windows is filled with ornamental iron-work, for the purpose of ventilating the vaults or catacombs. The flank of the church has a central projection, occupied by antae, and six insulated Ionic columns; the windows in the inter-columns are in the same style as those in front; the whole is surmounted by a balustrade. The tower is in two heights; the lower part has eight columns of the Corinthian order. Example taken from the temple of Vesta, at Tivoli; these columns, with their stylobatae and entablature, project, and give a very extraordinary relief in the perspective view of the building. The upper part consists of a circular peristyle of six columns; the example apparently taken from the portico of the octagon tower of Andronicus Cyrrhestes, or tower of the winds, from the summit of which rises a conical dome, surmounted by the Vane. The more minute detail may be seen by the annexed drawing. The prevailing ornament is the Grecian fret.
