I imagine the choice of the Drumcree parade was quite deliberate

This has been probably the most contentious of the Orange order parades in the six counties

The annual parade in the town of Portadown followed a 'traditional' route to and from Drumcree church which, over time, became a densely populated mainly-Catholic and nationalist quarter the residents of which sought to re-reoute the parade away from their area, seeing it as "triumphalist" and "supremacist".

'When the parade was banned from Obins Street in 1986, the focus shifted to the parade's return leg along Garvaghy Road.
In 1995, the dispute drew the attention of the international media as it led to widespread protests and rioting throughout Northern Ireland.
This pattern was repeated every July for the next four years. During this time the dispute led to the deaths of at least five civilians and prompted a massive police and army operation.

Since 1998 the parade has been banned from most of the nationalist area, and the violence has subsided' - Wiki
