Just around the corner from Camley Street Nature reserve is St Pancras Old Church.
There has been a church on this site since Roman times and part of the existing building dates back over a thousand years to the days of the Normans.
St Pancras Old Church's Parish once stretched way down South to Oxford Street and was an important establishment. It was situated near to the River Fleet which flowed down from Hampstead Heath to the Thames. The Fleet was buried as London grew over it and in Victorian times the Church itself fell into disrepair. Mans assault on Ma Nature eventually tore up the Graveyard to make way for the train lines to Kings Cross and St Pancras. Fascinatingly the Headstones that were removed were piled up around a tree in the Churchyard where they remain and the tree has grow amongst them even absorbing some of them into its trunk! Well worth a look.
