For bronze caster, Alex Agbonmwenre, the return of the Benin Bronzes is about far more than the return of looted artefacts. It is also a reminder that the craft, which found a patron in Benin 800 years ago, has continued through an unbroken lineage of master craftsmen, ever since. And those master craftsmen can be found today, in Igun Street, a UNESCO World Heritage site.
