A Welcome to Spring: Festival of Lights Zagreb from 20 to 24 March! This year Zagreb will again await and welcome spring with the Festival of Lights. From 20 to 24 March this event will enchant us with romance that will mark the life of Upper town squares, streets and facades. The Festival will take place in the historical centre of the city, in the romantic Upper Town. Owing to modern lighting solutions enabled by top notch lighting technology, the arrival of spring but also symbolical awakening, growth and renaissance will be accompanied every day from 6 to 11 PM by imaginative light shows, audio visual installations and projections.
