i was wondering, i've been down to Cambridge quite a few times now, and i've noticed there are some really pretty brass roses set into the slabs on the streets of Cambridge (particularly around Magdelene Street bridge on the way to St.Eds, Lucy C. and the Cavendish Lab)...
i was wondering, does anyone know what they mean, or why they are there? how old they are? etc.
i've not seen these in the many times i've been in Oxford, but let me know if you have them too.
