The Library of Celsus is a stunning Roman structure built in the 2nd century AD in Ephesus, Turkey. Commissioned by Gaius Julius Aquila to honor his father, Celsus, it once housed over 12,000 scrolls, making it one of the largest libraries of the ancient world. Its two-story facade features ornate Corinthian columns and statues representing Wisdom, Knowledge, Intelligence, and Virtue. The library’s grand design, with its impressive double walls, also protected the scrolls from humidity. Today, it stands as a testament to Roman architectural prowess and intellectual heritage.
