Prince Charles was confirmed at age 16 by Archbishop of Canterbury Michael Ramsey at Easter 1965, in St George's Chapel, Windsor Castle. He attends services at various Anglican churches close to Highgrove, and attends the Church of Scotland's Crathie Kirk with the rest of the royal family when staying at Balmoral Castle. In 2000, he was appointed as Lord High Commissioner to the General Assembly of the Church of Scotland. Charles has visited (amid some secrecy) Orthodox monasteries several times on Mount Athos as well as in Romania. Charles is also patron of the Oxford Centre for Islamic Studies at the University of Oxford, and in the 2000s, he inaugurated the Markfield Institute of Higher Education, which is dedicated to Islamic studies in a plural multicultural context.
