In Buganda's capital, Lubaga, Stanley found a well-ordered town of about 40,000 surrounding the king's palace, which was situated atop a commanding hill. A wall more than four kilometers in circumference surrounded the palace compound, which was filled with grass-roofed houses, meeting halls, and storage buildings. At the entrance to the court burned the royal fire, which would only be extinguished when the Kabaka died. Thronging the grounds were foreign ambassadors seeking audiences, chiefs going to the royal advisory council, messengers running errands, and a corps of young pages, who served the Kabaka while training to become future chiefs. For communication across the kingdom, the messengers were supplemented by drum signals.
