Tekfur Palace, built within Istanbul's ancient city walls in the historic Edirnekapı neighborhood, is a captivating remnant of Byzantine Constantinople. Built in the late 13th or early 14th century, it's the only surviving imperial palace from the Byzantine era, providing a rare and tangible connection to the city's medieval past. Originally known as the Palace of the Porphyrogenitus—referring to princes born in its purple-adorned chambers—Tekfur Palace served as both a royal residence and a strategic vantage point overlooking the Golden Horn. Today, after extensive restorations, visitors can wander through its striking brick-and-stone façade, admire the intricate masonry work, and explore exhibitions dedicated to traditional Ottoman tile-making, a craft famously produced on-site during Ottoman rule. Rich in history yet tucked quietly away from tourist crowds, Tekfur Palace offers locals and curious travelers alike an intriguing glimpse into Istanbul’s multilayered heritage. Do not miss especially if you are visiting the nearby Khora Mosque or Balat neighborhood.
