Millions of people watched the Coronation, which began at 11am and was followed by a procession from Westminster Abbey to Buckingham Palace.
Around 2,000 invited to the historic day, with thousands flocking to London to catch a glimpse of the procession or to share their thoughts on the monarch.
Met Police issued a statement about the "privilege" they felt after policing the event.
In total, 52 people were arrested in the capital for a number of offences, including breaching the peace, conspiracy to cause a public nuisance, sexual assault and affray.
Defending her force's actions today, the commander added: “We absolutely understand public concern following the arrests we made this morning.
“Protest is lawful and it can be disruptive. We have policed numerous protests without intervention in the build-up to the coronation, and during it.
“Our duty is to do so in a proportionate manner in line with relevant legislation. We also have a duty to intervene when protest becomes criminal and may cause serious disruption.
“This depends on the context. The coronation is a once in a generation event and that is a key consideration in our assessment.
“A protest involving large numbers has gone ahead today with police knowledge and no intervention.”
