The Crown was filmed in multiple locations across the United Kingdom, standing in for many royal residences and iconic sites. Key filming locations include:

• Lancaster House in London, which was used as a stand-in for Buckingham Palace.
• Ardverikie Estate in the Scottish Highlands, which represented Balmoral Castle.
• The Old Royal Naval College in Greenwich also contributed to Buckingham Palace scenes.
• Wilton House near Salisbury appeared frequently as parts of Buckingham Palace.
• Other notable locations include Ely Cathedral, Winchester Cathedral, Belvoir Castle (as Windsor Castle), St Andrews (university scenes), and York Minster (for royal wedding recreation).
• Hedsor House & Park near London was used as Downing Street for Thatcher scenes.

These locations were chosen for their historical architecture and resemblance to the royal estates and settings depicted in the show, as filming inside the actual royal palaces was not allowed.
