Charing Cross (WC2) Built on the site of Northumberland House. Was opened in March 1876. The Strand portion of the house is marked by the Grand Hotel, the opening of which, in 1880, was considered of so much importance that it was attended by the Lord Mayor and the Sheriffs. The Constitutional Club, the offices of the Royal Colonial Institute, and the headquarters of the Society for Promoting Christian Knowledge, are in Northumberland Avenue.
