Here’s how it works:

Participants in the treasure trail will be given a set of starting co-ordinates to find using a mobile internet service or sat nav for a location with historic significance in Birmingham City Centre.  When they go to the spot, they will find a costumed character with a historic link to the venue who will give them the location of the second clue and so on, until they have found four different re-enactors, each representing different periods of English history.

If you’re following the trail to find the fourth re-enactor, you’ll be entered into draws throughout the day to win family tickets to the Festival of History, which will feature re-enactments and things like a replica World War I trench, a medieval joust, and a Victorian travelling show.

The trail will be open for one day only, this Saturday 9th July, and the starting co-ordinates for the trail are 52.479433, -1.906933.
