On Sunday the Russian capital celebrated its 864th birthday. Military orchestras from more than a dozen countries marched in the "Spasskaya Bashnya" festival held in Moscow's Red Square.

The festival, which is named after the main Kremlin tower, has become a popular event in the Russian capital. Let's take a look at some of the festivities.

The annual military band festival kicked off in Red Square on Friday night. This year, "The Spasskaya Bashnya" or The Saviour's Tower, had some 1,500 participants from 14 countries.

Ten bands represented Russia, including the Presidential Orchestra.

The various groups performed classical, military, folk and national music accompanied by dances, displays of arms and folklore performances.

Over the years since the festival was first held in Moscow, the number of participating military bands from around the world has grown, attracting international media attention and bringing together thousands of spectators each day to enjoy the festival.

Fireworks and laser light shows crowned the military music program on Friday.

The tradition of organizing military band festivals dates back to the post-war years. After the end of World War II, it spread from the UK to other nations in the region.

The festival in Moscow starts some days ahead of City Day which is held annually on the first Sunday each fall, which this year was September 4th.
