Cambridge MP Daniel Zeichner was among more than 200 Beth Shalom Reform members and guests at the dedication of its new building on Sunday.
Leaders of a number of other faiths in Cambridge were among the congregation for a service led by Fiona Karet Frankl and addressed by senior Reform movement rabbi Laura Janner-Klausner.
Rabbi Janner-Klausner paid tribute to Beth Shalom's welcoming and inclusive nature, which was reflected in the remarks of synagogue chair Mike Frankl, who expressed a wish to help refugees and asylum seekers.
Mr Frankl said: "We have much to celebrate with our beautiful new synagogue open and in day-to-day use, creating a focal point for our community. This has not happened overnight and is thanks to all those dedicated volunteers who have organised fundraising, [the] purchase of a suitable site and managed the building process."
Beth Shalom caters to more than 200 families from Cambridge and the surrounding area and also welcomes students.
Some 70 children and 30 adults attend its Sunday cheder, one of the biggest synagogue religion schools outside of London.
