• Summer season only, as the city's open-air cinemas run from May to late September, depending on the weather
• Check the language first, since children's films in Greece are usually dubbed into Greek, while other films keep their original soundtrack with subtitles
• Cooler under the trees, as the National Garden next door drops the temperature a couple of degrees on hot nights

Aigli Zappeiou has screened films under the trees of the Zappeion gardens since 1910, making it the city's oldest open-air cinema. A 2024 renovation added a 4K laser projector and Dolby 7.1 sound. The program mixes art-house picks, new releases and children's films. The canteen serves movie snacks plus a handmade deep-dish pizza, and the greenery of the National Garden keeps the evening air cooler.
