The North-West London Eruv launches this week, which is a big deal if you’re an Orthodox Jew living in its boundaries, as I am. On the Sabbath we aren’t allowed to carry things around in public areas (i.e. outside our houses and gardens), but the eruv is a special kind of construction that marks a much larger boundary that makes carrying permissible. It’s a weird kind of hack in Halacha (Jewish law) but we’re not the first by a long shot – many cities worldwide have had eruvim for quite a while now. It’s just taken so long in London because of a stupid level of politics over something that ultimately consists of about eight strategically-placed poles and a few wires.
Thing is, those wires and poles are fragile, so the eruv has to be checked every week. If there’s a problem, the whole community has to be alerted so that we don’t end up using an eruv that isn’t there. This is where the website comes in – in the top-left corner of the front page you’ll see a traffic light image and some text that indicates (this week anyway) that the eruv is up and running.
(Yes, I do know how weird this all sounds. It’s strange and silly to me, and I’ve grown up with it.)
