This pub is not only a grade II listed building, it is also a Two Star pub on the Campaign for Real Ale’s (CAMRA) National Inventory with an interior of very special national historic interest, and the description is as follows: "This popular pub is but a small part of the massive Park Mansions retail and residential redevelopment designed by architect G D Martin: it is located in the phase that was built in 1900-2. There had been a pub on the site for generations and thus we have an interesting example of continuous usage for the licensed trade. The name commemorates Joseph Paxton who designed the Crystal Palace which once stood nearby. Superlative etched and cut glass can be found lining the walls and in doors and baffles. Motifs include grotesque masks, mythical birds, fruit, flowers and swirling foliage – all stock features in the repertoire of contemporary pub glass designs. Note the doors at the rear right which have PH monograms.

The bar counter with its panelled front and the ornate stillion in the middle date back to 1902, as does the central lobby with clock above. There is also an attractive Lincrusta ceiling with foliage decoration. Originally there would have been subdivisions surrounding the counter but these have all been swept away. The superstructure on the counter and bridges to the side walls are modern work."

HISTORY: Licensed premise has occupied the site since at least 1632 when it was known as the King's Head. From the 1760s it became known as the Granby's Head or the Marquis of Granby's Head. In 1851-3 it was rebuilt and took the present name. The building is highly unusual in that it has retained its ancient usage within a large modern development. A fine example of an ornate pub of c.1900 which retains its island servery and many of its other contemporary fittings."
