The Central Axis is the idea that gave Beijing its shape: a single north-south line drawn through the middle of the old city, with the emperor's palace at its centre and the altars, gates and markets arranged in symmetry around it. It runs roughly 7.8 kilometres from the Yongdingmen gate in the south to the Drum and Bell Towers in the north, and in July 2024 UNESCO inscribed it on the World Heritage List as a masterpiece of urban planning rather than as a single building. Walking it end to end is the cheapest way to understand why the city looks the way it does.
The southern half
Start at Yongdingmen, the reconstructed gate that marks the old southern edge, and walk north along the median. The Temple of Heaven sits to the east and the Altar of the God of Agriculture to the west - the two ritual complexes balanced on either side of the line. You then pass through the Qianmen area, where the Zhengyangmen gate and its arrow tower stand at the point where the ceremonial axis crossed the city wall, and into Tiananmen Square, with the Monument to the People's Heroes and the Mao Zedong Mausoleum planted directly on the line.
Through the palace and out the other side
The axis continues through the Meridian Gate into the Forbidden City, and from the north gate it climbs Jingshan, the artificial hill built from the excavation of the palace moat, whose Wanchun Pavilion sits on the exact centre line. Beyond that comes the Drum and Bell Towers and the old commercial streets around them. The whole route is flat and paved, and you can break it anywhere: the metro runs parallel on several lines and the walk can be done in two or three shorter stretches.
Practical notes
The Forbidden City section requires a timed ticket booked in advance through its official channel, and it closes on Mondays; Tiananmen Square also needs a free reservation. Everything else on the axis is public street or parkland. Spring and autumn are the comfortable seasons, and early morning is the only time the square and the Jingshan climb are close to quiet. Allow five to eight hours if you want to stop inside the palace and at the temples, or about two and a half hours if you walk straight through.
