Though Queen Elizabeth's 60-year reign has been marked by a variety of both challenges and triumphs, there's been one constant: her commitment to service.

The Queen was recognized for her dedication to public service in a ceremony at St. Paul's Cathedral Tuesday during the Diamond Jubilee. The Archbishop of Canterbury, Dr Rowan Williams, gave the homily honoring the Queen, according to theprovince.com.

"We are marking six decades of living proof that public service is possible and that it is a place where happiness can be found,"he said.

People who want to show gratitude and appreciation for the Queen with gifts have been asked donate money to The Queen Elizabeth Diamond Jubilee Trust, an organization that aims to extend her dedication to service for years to come.

The Trust will support organizations that focus on youth leadership, urban food accessibility and greater quality of life for people living with disabilities, among other causes.

The Diamond Jubilee also honored other individuals for their dedication to service -- including five crew members of the Kent, Surrey and Sussex Air Ambulance Trust.

The Air Ambulance Trust, set up in 1989, is an emergency helicopter that can reach Kent, Surrey and Sussex in 20 minutes, and responds to between four and six emergencies each day. According to BBC, Pilots Blaine Ashurst and Kevin Goddard and clinical managers Gary Wareham, Rob Wilkinson and Richard de Coverly received Diamond Jubilee medals for their work.
