On a pillar opposite the door in the North Aisle stands a statue of St Martin dressed as a Roman soldier.  Many important people have visited the parish of St Martin – King Charles I worshipped here twice.  One of his friends was Sir John Whatton, the High Sheriff of Leicestershire, whose memorial and that of his two wives is placed on the north wall.  In the North Transept there is a large painting “The Scourging of Christ” and a three panelled piece (known as a triptych).  Against the tower pillar is a tombstone, re-used several times since 1400, and above it is the carved frieze from the original Norman stonework.

The Great South Aisle was added about 600 years ago.  It was a special part of the church with a special altar dedicated to St Mary, the mother of Jesus.  In the south-east corner three seats are to be found recessed into the wall for the use of the priests and assistants at the Mass, and also the remains of the sink used for washing the chalice and paten.  Water drained into the foundations, thus preventing ‘witches’ from collecting the water for magic purposes.  The altar is not there any more but has been replaced by the Archdeacon of Leicester’s Court, where cases involving church law were heard.  The Royal Arms are those of the first three Georges, 1714 – 1801.  The chapel was used by the Guild of Corpus Christi which was founded in 1343.  They used to have meetings in the Guildhall after they had been to church.

The large east window shows Jesus going up into Heaven.  All the other windows here are about things that Jesus did after he rose from the dead and before he ascended.  In a corner near to St Dunstan’s Chapel there is a memorial to Vivian Redlich who was a missionary in the Far East.  He was executed during the Second World War.
