Like many pocket parks, this is the result of too many people dying too often -- it's a disused graveyard.
Just to the south of Old Street can be found one of London's oldest and greatest burial grounds, and one with a most unusual history.
London's newest Pocket Park opened a couple of weeks ago, replacing an ugly road junction that was a legacy of 1960s thinking.
A gas lamp lit shady rectangle of grass providing relaxing seating next to a church for a She-Wolf.
This is rather forlorn pocket park of the sort that only a mother could love, sitting in the corner of a corner of two busy roads.
On a side street, just about visible from the main road, lies one of London's greatest so-called hidden delights.
This, as so many of the City of London gardens is the site of former religious worship, but unlike most other gardens, this isn't the graveyard, but the remains of the church itself.
Following the recent departure of the US Embassy, plans are afoot to revamp the neighbouring Grosvenor Square now that the security paranoia has moved away.
A few miles from its fictional location, there is a very real Albert Square and it has a large open garden in the heart of the square.
Apart from it's boxy architecture, the US Embassy in London is also noted for the lake and garden that surround it.
