The latest United Synagogue eruv is now operational in Belmont, north-west London.
An extension of the Stanmore eruv, the religious boundary covers around 4,000 homes surrounding Belmont Synagogue. It was in use for the first time on Shabbat.
The Belmont congregation had supported an 18-month campaign to raise funds, launch the planning application process, get the poles and wires in place and run initial maintenance checks.
Campaign chair Anthony Broza said the eruv had been “created, funded and constructed at breathtaking speed, demonstrating the Belmont community’s desire to have an eruv as part of its religious infrastructure”.
