Sir – We applaud indeed the initiative that allows smartphone users to hear stories behind the memorials to soldiers buried in Botley cemetery (Cemetery is first to be smartphone compatible, November 15). But we must point out that St Mary & St John's churchyard in East Oxford can make a similar and prior, claim! In the spring this year, funded by a Big Lottery Community Wildlife grant, we launched four educational nature and local history trails that can be accessed by a QR code posted in a display board near the south porch of the church facing the churchyard.

There is a flora trail, a wildlife and conservation trail, a history trail, and a trail with a selected blend of the other three. By means of the smartphone and GPS location technology, the visitor is guided round the two-acre Victorian churchyard with ten to 12 interest points per trail.

At each point there is text information, photographs and a quiz question. To help maximise the educational potential of the trails, there is a teachers and visitors guidance document on the website: www.ssmjchurchyard.org.uk and suggestions for follow-up projects on each of the three topic areas.

The SS Mary & John churchyard group would be pleased to provide further information and would welcome feedback.
