This event falls every year on the first Saturday after Europe Day on May 9. This date marks the signing of the Schuman Declaration on May 9, 1950, which established the European Coal and Steel Community, a multinational entity that would eventually become the European Union as we know it today.

We celebrate Europe Day by opening our doors to the public so that Americans can catch a glimpse of the European cultures that make up the European Union. Normally you have to cross the Atlantic to visit the EU, but at Open House, you just have to cross the street!

See you in 2026!

We express our sincerest appreciation to the 2025 sponsors and partners that made this year's Open House possible!

Now, nearly 20 years later, Pupatella is a household name for Neapolitan pizza throughout the Washington, DC region, is the largest VPN Certified Pizza Group in the United States, has been named a World Artisan Pizza Chain – Excellent Pizzeria by the prestigious 50 Top Pizza and more.

Before visiting the EU Delegation and most of the participating embassies, please take note of these helpful guidelines.

• Entrance to the participating buildings is always FREE, but some may be selling food or other items on their premises.
• Always carry official ID with you, as some embassy security requires it before entering.
• Avoid bringing large bags or backpacks, as some embassies have security screenings that require cumbersome bag checks.
• Driving and parking is strongly discouraged due to many embassy locations. We encourage participants to take the Metro, bus, scooter, rideshare, or walk.
• Not all embassies have disability access or stroller parking.
• For some embassies, you can expect to wait in line. Consider arriving to your favorite embassies earlier in the day.
