Corvey core zone seems to extend beyond the Westwork. The core zone on the Unesco map covers the whole monastery area.

An update, after New Zealand, I did a mix of sites:
Amsterdam Canal Ring
Ancient City of Aleppo
Ancient City of Bosra
Ancient City of Damascus
Site of Palmyra
Surtsey
Thungyai-Huai Kha Khaeng
Tropical Rainforest Heritage of Sumatra. (c) Protected Planet
Ujung Kulon
Lorentz National Park. (c) Protected Planet
Komodo National Park
Dholavira

Regarding the Amsterdam Canal Ring, I am always amazed by how specific it is.
I have removed the Botanical Garden connection, as the Hortus Botanicus lies just outside.
We can use more POIs here, but none of the reviewers, except Hubert, have indicated any that are actually within the core zone.

Lots of India in today's crop. Overall Indian map quality is poor; some locations, such as the Taj Mahal or Agra Fort, don't even have an official map.

Ajanta Caves
Rani-ki-Vav
Kakatiya Rudreshwara (Ramappa) Temple
The Jantar Mantar, Jaipur
Red Fort Complex
Keoladeo National Park
Yosemite National Park
Khangchendzonga National Park
Great Himalayan National Park Conservation Area
Carolingian Westwork and Civitas Corvey

How can I help? I have my own maps, very accurate

I will send you a pm

Roamed around Asia today, but it was hard (Pakistan, Bangladesh, Cambodia, pfff). More happy with Uzbekistan, where they provided satellite maps with the core zone pencilled in.

Bukhara
Itchan Kala
Shakhrisyabz
Makli
Rohtas Fort
Phong Nha-Ke Bang National Park and Hin Nam No National Park
The Sundarbans
Lumbini, the Birthplace of the Lord Buddha

Another case of Incorrect UNESCO number of locations: Saryarka
The list shows 5 locations, of which one is: "Naurzum State Nature Reserve – NSNR Eco-Corridor linking the upper cluster (only buffer zone)"
On the map it is clearly shown as separate and in a different colour from the core zone and the number of hectares in the core zones according to the AB ev is 0, so this is not an official component as we see it. It is only a special kind of buffer zone

For Sulaiman-Too the core zone is straightforward, except for a little detour the boundaries make across the street to include The Mosque of Mohammed Yusuf Bai Haji Ogli (Boqiy). It dates from the early 20th century (see this link). Will add it to the "Contains significant structures from the 20th Century" connection

Yesterday's batch. The Gulf/Middle Eastern ones often use satellite maps which are quite reasonable to work with:

Walled City of Baku
Erbil Citadel
Ashur
Kinderdijk (thanks Frédéric! his first...)
Hatra
Babylon (large core zone)
Al Zubarah Archaeological Site
Ancient City of Qalhat (larger than I expected)
Bahla Fort (huge! includes much more than the fort, the whole oasis and beyond)
'Uruq Bani Ma'arid
At-Turaif District in ad-Dir'iyah
Hegra
Petra (interesting to see with the POIs added how large the actual area is)
Parthian Fortresses of Nisa
Kunya-Urgench
Sulaiman-Too Sacred Mountain
Mausoleum of Khoja Ahmed Yasawi
Saryarka

Roaming around in North Africa and Turkey. Morocco's maps are very poor and the Turkish ones are hard to interpret as well. Remarkably, both at Troy and Catalhoyuk, surrounding agricultural fields are included: maybe they see archeological potential here, or are the maps just imprecise? And Diyarbakir has the big enclave of course.

Thanks to meltwaterfalls for rediscovering his advanced mapping skills:
- Bamiyan Valley (with adjusted coordinates for virtually all locations, they are very wrong at the UNESCO website)
- Minaret of Jam (including new location for Jewish cemetery)
