The Life Guards (Swedish: Livgardet, designation LG) is a combined Swedish Army cavalry/infantry regiment. Its responsibilities include the defence of Stockholm as well as provision of the royal guard of honour for the King of Sweden and the Stockholm Palace. With traditions dating from 1521, the regiment is one of the oldest military units in continuous operational existence in the world. It was established in its present form in July 2000, following a merger of the Svea Life Guards and the Life Guard Dragoons. Headquarters are mainly located in Brunna north of Kungsängen in Upplands-Bro Municipality and at the "Cavalry Barracks 1" in central Stockholm.
