Ten Acres; maybe

The Ordnance Survey map of this area near where we are staying includes a label, 'Ten Acres', giving it similar prominence to names like Stirchley and Kings Heath, which are local government entities. The name survives in a few local road and business names, but not as a clearly defined area. Google applies the name to a "Nature Space" in roughly the same spot; I think that's the product of a local group of enthusiasts who have adopted the name for part of the linear park that runs almost all the way from here to the city centre

A local history web site says the name originated from a farmer's field, which rings very true - one or two fields on many farms are often named after their area (on my childhood home farm, we had one called 'The Little Bits'). The field name, it says, was applied to a 19th century housing development, and revived for 20th century housing, but the location is not the same and there is only semi-wild park in the area now labelled Ten Acres, and no housing with that name. Another web site shows the relevant section of the 1921 OS map. The label is still there, but in a different place that is neither the current parkland or the supposed site of the ten acre field

Having said all this, there clearly was a place called Ten Acres with a distinct enough identity that when the first Co-operative society store was founded in this district, in 1875, a couple of hundred metres from all of the putative sites of Ten Acres, it was called 'The Ten Acres and Stirchley Co-operative Society'. This was eventually subsumed into the larger co-op movement, and a store operated on the main street until 2020 when, sadly, the site was transferred to Morrisons

This Ten Acres other claim to fame is that it marks the end point of the Bourne Brook - the one that flows through the Cadbury chocolate factory and gave its name to the neighbouring Bourneville district, where the family built model village-style staff housing, and of course to the famous chocolate bar. This is not a picture of the Bourne Brook, it is the river Rea, just downstream of the confluence, demontrating that even a city park can look pretty good on a bright spring day as birch and willow start to flaunt their seasonal colours
