The Castle Inn was located at 42 Nicolas Street, on the corner of Blackfriars and next door to what is now a PC business with the modern Conservative Club above.

Along with an adjoining row of cottages (nos. 30-40 Nicolas Street) it was demolished in 1974 as part of the construction of the Inner Ring Road. The inn's sign has been removed so the photograph may have been taken not long before the pub disappeared.

The licencee in 1850 was Robert Wooley Evans, who was still there in 1880, in 1902 Mrs E H Williams and in 1910-14 W E Higginson. It was listed in the History, Gazetteer & Directory of Cheshire, 1850, the 1859 Post Office Directory of Cheshire and Slater's Directory in 1880.

Below we see a detail from the 1875 Chester OS map showing the Castle Inn's location- on the corner of Blackfriars and across the road from Whitefriars and the ancient St. Martin's Church- which, after standing here for a thousand years or so, also vanished in the name of progress when the Nicolas Street stretch of the Inner Ring Road was constructed. Previous to this, this section of the road, where once the west wall of the Roman fortress of Deva ran, was known as St. Martin's Ash.
