Scallops

According to this article (and video supplied there) the bells for the Queen's Jubilee are actually for the St James Garlickhythe, a church in London. Once the Jubilee is over, the church will get them.

It gets more interesting when you learn the church was destroyed in the Great London Fire of 1666.

The church is all about the scallop shell (they stamp passports and such with a scallop shell logo.)

Princess Diana's sons commemorated their mother by having scallops placed on their coat of arms.
