Exploring our surveying antiques

The prospect of the upcoming move to our new head office has resulted in buzz of increased activity around the building in recent months. Just like when you move house, it’s been a good time to have a bit of a clear out and take stock of what’s been hiding under the proverbial bed or in the attic.

Well, part of that process has included cataloguing the many pieces of antique surveying equipment that have been accrued by Ordnance Survey over the past 200 years. Some of the items have played an historic role in the birth of modern map making in Britain and are irreplaceable.

To understand more about some of this fascinating equipment, I caught up with Ken Lacey, a surveyor by trade who now works in our education team. Ken was kind enough to give me a tour of what is rapidly turning into an Aladdin’s cave of cartographic memorabilia, with two pieces being of particular interest. Read More


Visiting the Director General’s House

Vanessa Lawrence, our Director General recently paid a visit to a particularly special building in Southampton. 15 Rockstone Place is near the centre of the city and is now the home of a solicitors firm, but it for many years it had a very close association with Ordnance Survey as the ‘Director General’s House’.

The house was built in 1840, and was one of the last projects of Samuel Toomer, who died in 1842 at the age of only 41. It was originally called Avenue House and for the next 25 years it served as a private residence. Read More


Bronze Age farm discovered at OS head office

I met up with Wessex Archaeology recently to find out about the previous residents at Adanac Park, the site of our new head office.

Back in 2008, as part of the planning process, Wessex Archaeology were asked to investigate the site for historical interest. They were fairly confident of finding some archaeological remains as there had been finds at sites in the local area, but were surprised to find evidence of a late Bronze Age farm, the first of its kind in this part of Hampshire.

Archaeologist Andrew Fitzpatrick told me, ‘The site proved to be late Bronze Age, around 3,000 years old, four or five houses and evidence of smaller structures, such as storage sheds and granaries. There was also an Iron Age burial ground with seven barrows and other graves. This was quite unexpected and the site is unique in Britain.’ Read More


The history of the OS Explorer Map

Here’s the first in our two part series on the history of the OS Explorer map.

OS Explorer Maps – the beginning

The iconic OS Explorer Map, used daily by thousands of people from ramblers to rock climbers and named by the Design Council as an official millennium product, has a fascinating history. Did you know, for example, that it wasn’t until 2005 that the whole of Great Britain was covered, including remote areas of the Scottish Highlands?
