The large bare and gaunt structure in Sardinia Street is the old Embassy Chapel, which dates from the seventeenth century, and the sanctuary portion of which is held to be the work of Inigo Jones. Its large vaulted ceiling is certainly in his manner, and suggests the arcades at Covent Garden. The faded old gilding and foreign decorations of the interior, the painted pillars and capitals, and the curious tiers of galleries, like the stern of a Spanish argosy, are interesting; and we call up the turbulent nights of the Gordon Riots, when it was sacked and set on fire. In one of the houses opposite Franklin lodged, with a pious Catholic widow, when he was pursuing his trade as a humble printer. The side of the Fields adjoining the chapel has a particular interest from the stately houses before alluded to. We may note the large, well-carved roses and fleur-de-lys which ornament them, and Inigo’s favourite type of stone pilasters and capitals on a brick ground. The finest and most picturesque old house to be seen in London, close by, in Great Queen Street, is also his work, and almost as he left it. The roof and the enriched capitals and bold cornices are very striking; but the lower portion has long been a shop, which makes the whole look insecure. At the corner of this street, and looking into the Fields, is the great mansion of the notorious and intriguing old Duke of Newcastle, with its courtyard in front and sweeping flight of steps--a very striking pile, with its fine stairs and stately and spacious apartments, now devoted to offices. A few doors lower down we are arrested by a large open paved courtyard, with two enormous piers capped by gigantic vases of the most massive and florid kind. Here there now appear to be two houses; but a second glance shows us that this is another imposing mansion, with a handsomely designed front, which the moderns have cut up into two: it was, in fact, the residence of the Lindseys, Earls and Dukes of Ancaster. Another mansion of theirs, even larger, is still to be seen on the Chelsea Embankment, close to Battersea Bridge. Often from familiarly we overlook much that is interesting; but this house in Lincoln’s Inn Fields proclaims its ancient significance in a striking way. Next to it is a granite mansion of the Lord Burlington era, with an elegant and original semicircular portico, also divided into two houses.
