The Royal Edinburgh Military Tattoo is an annual series of military tattoos performed by the British Armed Forces, various international military bands, and civilian groups on the esplanade of Edinburgh Castle. It was inspired by a modest show titled ‘Something About a Soldier’ that took place in 1949 at the Ross Bandstand in Princes Street Garden. The following year, the first official Edinburgh Military Tattoo was held on the castle esplanade, featuring eight performances. Since its humble beginning, the event has evolved into a renowned international spectacle.

The term ‘tattoo’ originates from the early 17th-century Dutch phrase ‘doe den tap toe’ [turn off the tap]. It was a signal given by drummers or trumpeters to instruct innkeepers near military garrisons to stop serving beer, prompting soldiers to retire to their lodgings. In the 18th century, the term ‘tattoo’ referred to the final duty call of the day. Over time, the performance has transformed into more of a show. In the late 19th century, military tattoos became common, with many military and garrison towns hosting summer performances.
