The legendary Castle Illuminations every year capture the imagination of thousands of people - hardly any other city offers such magical nights every year in June, July and September.
Bengali flares slowly bathe the Heidelberg Castle in a mysterious red firelight, as if the ruins were on fire once again in their long history. As the last times in 1689 and 1693, when the troops of the Sun King Louis XIV burnt down the castle, leaving behind the world-famous ruins.
When the glowing Castle slowly dies down, the second part of the spectacle begins - the brilliant fireworks over the Neckar. The Elector Friedrich V first had the fireworks staged in 1613, in order to provide a fitting welcome for his newly-betrothed wife Elizabeth Stuart. These fireworks laid the cornerstone for the later festivals of light held in the night sky over Heidelberg.
The banks of the Neckar, the Nepomuk terrace and the Philosophers' Walk around 10 o'clock are the best locations to admire the Castle Illuminations.
