The Library of Celsus was built in the Anatolian city of Ephesus during ancient Roman times, but today its remains stand in what is now the city of Selçuk in western Turkey. Built in the early second century A.D. in honor of Roman Senator Tiberius Julius Celsus Polemaeanus, the library originally served as his mausoleum and a place to store 12,000 scrolls, making it the third largest library in the ancient world. While the building’s interior was sadly destroyed in the third century and the façade took a hit in the 10th or 11th, the latter was re-erected in the 1970s and continues to be a breathtaking sight, particularly when lit up at night.
