Given the following context:  Radcliffe Tower is all that remains of an early 15th-century stone-built manor house.  The structure is a Grade I listed building and protected as a Scheduled Monument.  The construction of a nearby tithe barn is not documented, but it was probably built between 1600 and 1720. It was used for storage of the local tithes (a tenth of a farm's produce).  Along with Radcliffe Tower, the Parish Church of St Mary is a Grade I listed building.  The town also has two Grade II* listed buildings; Dearden Fold Farmhouse, completed during the 16th century, and Radcliffe Cenotaph, built in 1922 to commemorate the First World War.  Outwood Viaduct, and Radcliffe's most visible landmark, St Thomas' Church, are Grade II listed buildings.  St Thomas' took nine years to complete. The first stone was laid by Viscount Grey de Wilton (grandson of the Countess Grosvenor) on 21 July 1862, and it was consecrated in 1864 by the first Bishop of Manchester, James Prince Lee.  Construction of the tower began in 1870 and the building was completed in 1871.  The building cost £7,273, (£670 thousand today) and the tower cost £1,800 (£160 thousand today). The first vicar was the Reverend Robert Fletcher. Radcliffe's first public ornament was a drinking fountain located at the bottom of Radcliffe New Road.  It was presented to the town by a Mrs Noah Rostron in memory of her husband, and erected in August 1896.  The fountain no longer exists at this location. Built in 1911 the town hall was on the junction of Water Street and Spring Lane.  For many years after the town lost its urban district status, the building was unoccupied.  It was converted to private accommodation in 1999.  answer the following question:  What two buildings are Grade I listed buildings?
