As of my last knowledge update in January 2022, there wasn't a specific "Night at Casa Batlló tickets" event or experience where visitors could explore Gaudi's iconic house after dark in a special program. However, it's possible that new events or experiences have been introduced since then.

Casa Batlló tours, located in Barcelona, Spain, is one of Antoni Gaudí's masterpieces and is known for its unique architecture and design. The house is open to the public during regular hours, allowing visitors to explore its distinctive features, including the fantastical façade, impressive interiors, and the famous dragon-shaped roof.

To find the most up-to-date information on special events or nighttime experiences at Casa Batlló, I recommend checking the official website of Casa Batlló or contacting them directly. Event schedules and offerings can change, so it's always a good idea to verify details before planning your visit.

If there have been new developments or events introduced after my last update, you can also search for recent reviews or news articles for the latest information on unique experiences at Casa Batlló, especially those that may take place after dark.
