The Queen and Prince Philip got a warm welcome when they arrived at Chelmsford Cathedral this morning.
It was the first stop on their visit to the county today which also includes a trip to Felsted School for lunch.
They were invited to the cathedral as part of the diocese's centenary celebrations and later met staff and volunteers based there.
Well-wishers lined the streets of Chelmsford - and hung out of their windows - this morning to see the Queen and the Duke of Edinburgh arrive in the city.
The royal visitors have now moved on to Felsted School, near Dunmow, which is celebrating its 450th anniversary.
They will enjoy a very special school dinner and meet staff and students.
The Queen will also open the school's new boarding house, which replaces one that was destroyed in a fire in July 2012.
