Hangzhou's West Lake marks 15 years as a UNESCO World Heritage site
Hangzhou's West Lake is marking 15 years as a World Heritage site, after it was added to the list in 2011.
The lake is a cultural landscape known for its scenery and long history, and it is also part of the city.
Managers now use AI and digital monitoring to spot risks, including damage to historic sites and overcrowding at popular spots.
In 2025, AI alerts identified 18,000 problems, and all were addressed, according to the report.
Restoration work has also helped create an underwater forest, while the lake's water meets the stated standard for surface water class III.
The lake's parks remain free to enter, in line with a public-access commitment made after the heritage listing.
Officials are expanding AI tools for protection and visitor services, including a new system for guides, route planning and bookings.

What people are saying
Now world heritage sites are entering the AI era, and protection models traditionally reliant on manual inspections, experience-based judgment and after-the-fact repairs are gradually being replaced by a digital-intelligence system centred on big data, artificial intelligence and spatial observation.
The scenic area’s management has shifted from relying more on large numbers of staff and experience-based judgment to using AI technology and a smart network to take on West Lake’s digital management.
Choosing the planting site, improving the substrate, matching species, planting methods and timing are all crucial, along with careful daily maintenance to ensure the submerged plant community remains stable.
Waterbirds are the spirits of West Lake; we love West Lake, so we have voluntarily become its guardians.
