Location & Transportation

Nestled on the forested slopes of Purple Mountain (Zijin Shan) in Nanjing’s Xuanwu District, the Purple Mountain Observatory, Chinese Academy Of Sciences sits at No.1 Purple Mountain Observatory Road. To get there, take Metro Line 2 to Xiaowei Street Station, then hop on Bus 34 or 201 for a 20-minute ride. Taxis are also convenient, though be prepared for winding roads up the mountain.

Natural Scenery: A Green Escape

Surrounded by lush forests and hiking trails, the observatory offers a peaceful escape from city hustle. Spring brings cherry blossoms and fresh air, while autumn paints the mountains in red and gold. The observatory’s terrace provides panoramic views of Nanjing’s skyline, blending urban landscapes with nature’s tranquility.

Cultural & Historical Highlights

Built in 1934, the Purple Mountain Observatory is China’s oldest and most iconic astronomical site, nicknamed the “Cradle of Modern Chinese Astronomy.” Inside, you’ll find ancient Chinese stargazing tools, like gilded bronze astronomical instruments from Ming and Qing dynasties, alongside modern marvels like a 60cm reflecting telescope made entirely in China.

This was the first government-run modern astronomy institute in China, once dubbed “the best in East Asia” for its research. Roaming its halls feels like stepping through time—from medieval star charts to digital planetaria.

Facilities for Visitors

The observatory is tourist-friendly: a parking lot, a small café, and clean restrooms make visits hassle-free. Free Wi-Fi and English-speaking guides are available. For kids, interactive exhibits demonstrate astronomy basics, while a souvenir shop sells star-themed kitsch.

What to Expect During Your Visit

Start at the Purple Mountain Observatory’s main hall, where vintage telescopes and historical photos tell the story of China’s space journey. Climb to the rooftop observatory for sunspot-viewing sessions (check schedules online!). At night, join guided stargazing tours (weather permitting) using their powerful telescopes.

For non-astronauts, the real highlight might be the 360° view of Nanjing from the terrace. On clear days, you can spot landmarks like Xuanwu Lake and the city’s iconic gate towers.
