Ephesus was an ancient Greek city located in what is now western Turkey, near the modern-day town of Selçuk. It was once a thriving port city, known for its impressive architecture, advanced engineering, and rich cultural history.

The city was founded in the 10th century BCE by Greek colonists and became one of the most important cities of the ancient world, thanks to its strategic location and thriving economy. In the 2nd century BCE, it came under the control of the Roman Empire, and it continued to prosper as a major commercial and cultural center throughout the Byzantine era.

Ephesus was home to several impressive monuments and structures, including the Temple of Artemis, one of the Seven Wonders of the Ancient World. Other notable buildings in the city included the Library of Celsus, the Great Theatre, and the Temple of Hadrian. The city was also home to the House of the Virgin Mary, believed by many to be the final resting place of the mother of Jesus.

Today, visitors to Ephesus can explore the ancient city and marvel at its well-preserved ruins. The site is a popular tourist destination and is recognized as a UNESCO World Heritage site. It offers a glimpse into the vibrant culture and sophisticated architecture of the ancient world, and is a testament to the enduring legacy of one of the world's most influential civilizations.
