The City of London swords are five swords that the City of London has for special occasions. They are the Mourning Sword (or Black Sword), the Pearl Sword, the State Sword (or Sunday Sword), the Old Bailey Sword and the Mansion House Justice Room Sword. When the Lord Mayor goes outside the City of London sometimes he or she takes the Travelling Sword of State, which is different from the State Sword. They are kept at Mansion House, where the Lord Mayor of London lives.
