Edinburgh Festivals' Cavalcade
The Cavalcade sees performers from all the Edinburgh Festivals roll through the city in an annual procession at the beginning of August. It usually takes place on the first Sunday of the month, but in 2009 is scheduled for Sunday 9 August.
There was a question mark over whether the event will go ahead in 2009 as the Edinburgh Tram Project is laying tracks on Princes Street - a main part of the route - from February to November. However, the event relocated to Holyrood Park.
The Cavalcade first took place in 1976.
Over 175,000 spectators typically crowd into the streets for the event.
Parade of floats
Due to construction work on Princes Street, in 2009 the Calvalcade starts at 2pm at the Holyrood Park Road entrance (by the Commonwealth Pool) and travels north and east along The Queen's Drive.

Princes Street route
In 2010 the Calvalcade is expected to be back to its normal route: a motorised cavalcade sets off from Market Street near Waverley Station at 2.30pm. It is followed by the entire cast of the Edinburgh Military Tattoo and over 3,000 participants from Edinburgh's various Festivals, Fringe shows, Community Groups, Commercial floats and bands from all over the world.
The route goes over Waverley Bridge, along Princes Street into Lothian Road and finishes at the end of Castle Terrace.
There is grandstand seating on the North Side of Princes Street.
