MKII

The MKII sits in Greater London as a proper slice of British engineering heritage - a Second World War-era radar station that actually still stands. It's the sort of thing you'd drive past without noticing unless someone pointed it out, which is exactly why it's worth seeking out.

What you're looking at is a working example of the technology that helped win the war. The station itself is modest - no grand facades or sweeping grounds - but that's rather the point. This was functional wartime infrastructure, built to do a job and then left largely alone when the conflict ended. The appeal is entirely for those who get genuinely interested in the mechanics of early radar systems and the role they played in the Battle of Britain.

Historically minded visitors and engineering buffs will find real satisfaction here. Kids will likely find it a bit dull unless they're already into military history - there's no interactive elements or themed attractions, just the raw fact of the building itself.

Access and opening details aren't straightforward - you'll need to ring ahead or check online before heading out. If you're staying at Lee Valley Camping and Caravan Park up in Edmonton, it's close enough for a morning detour, though it won't fill a day on its own. Combine it with other Greater London landmarks rather than making it a sole purpose trip.

Worth a look if you're local or genuinely fascinated. Otherwise, it's a specialist interest rather than essential viewing.
