Crowds gather in Riyadh and Ad Diriyah to mark Saudi National Day, waving green flags, joining street festivities and watching a Saudi military parade.
Traditional performances and decorated cars add to the atmosphere.
For many residents, the annual event is a chance to spend time with friends and family. Some say taking part has become a long-standing tradition.
This year's festivities come amid heightened regional tensions involving Yemen's Iran-backed Houthi group. Fireworks and drone shows planned across Saudi Arabia were postponed until further notice.
National Day is held each year on September 23.
