    I’m sure I’ve seen this before, but I always forget it. Browsable historical Ordnance Survey maps of the UK.

    This 1881 map is an amazing work that shows the travel time from London to... everywhere. Not only is it one of the first isochronic maps (marking distances that could be traveled in the same time) but it drew on steamship tables, post office records, and private voyage records.
