The easiest way to see if a connection already exists is to use the search field at the top of the connections homepage (the grey box labelled Connections). When you click on it a free search box appears independent of the categories which indeed are a bit arbitrary.

The one at Stara Nekrasivka (Ukraine), though, looks like an obelisk to me :) Or maybe it's not tall enough to qualify as such?

I'd like to propse another one under "Individual People Connections": Xuanzang

Xuanzang, born Chen Hui / Chen Yi, was a Chinese Buddhist monk, scholar, traveler, and translator who traveled to India in the seventh century and described the interaction between Chinese Buddhism and Indian Buddhism during the early Tang dynasty.

- Ajanta Caves - Xuanzang visited Ajanta.
- Bamiyan Valley - In Bamyan, Xuanzang met the king and saw tens of non-Mahayana monasteries, in addition to the two large Buddhas of Bamiyan carved out of the rockface.
- Buddhist Vihara at Paharpur - After Nalanda, Xuanzang traveled through several kingdoms, including Pundranagara, to the capital of Pundravardhana, identified with modern Mahasthangarh, in present-day Bangladesh. He also visited Somapura Mahavihara at Paharpur in the district of Naogaon, in modern-day Bangladesh. The modern-day vihara however dates from the 8th century AD, after Xuanzang.
- Grand Canal - The Grand Canal passes through Luoyang, where Xuanzang was ordained as a śrāmaṇera (novice monk) at the age of thirteen.
- Lumbini - In 636, Xuanzang traveled through Terai in the southern part of modern Nepal, where he found deserted Buddhist monasteries, and thence to Kapilavastu, his last stop before Lumbini, the birthplace of Buddha. In 637, he set out from Lumbini to Kusinagara, the site of Buddha's death.
- Mahabodhi Temple Complex - Xuanzang visited Bodh Gaya in 637.
- Nalanda - After Bodh Gaya, Xuanzang went to Nalanda, the greatest Indian university of the Indian state of Bihar, where he spent at least the next two years.
- Samarkand - Xuanzang crossed the desert from Tashkent further west to Samarkand. In Samarkand, the party came across some abandoned Buddhist temples and Xuanzang impressed the local king with his preaching.
- Silk Roads - The Silk Road passes through Luoyang, where Xuanzang was ordained as a śrāmaṇera (novice monk) at the age of thirteen. / After his return to China in AD 645, Emperor Gaozong of Tang ordered to install two stele stones in celebration of Xuanzang's extraordinary achievement at the Giant Wild Goose Pagoda. There is also a statue of Xuanzang at that pagoda.
- Taxila - Xuanzang visited Taxila, which was desolate and half-ruined, and found most of its sangharamas still ruined and desolate.
- Xinjiang Tianshan - In 629, Xuanzang traveled across the Gobi Desert to Kumul (modern Hami City) and then followed the Tian Shan westward to arrive in Turpan in 630. The hottest mountain in China, the Flaming Mountains, is located in Turpan and was depicted in the "Journey to the West", a Chinese novel that is an extended account of the legendary pilgrimage of Xuanzang.

He has one already, Jurre: https://www.worldheritagesite.org/connection/Travels+of+Xuanzang

Let me check if you found new connected sites - I'll add them.
P.S. at least you extended it and added notes for all of them, so the work was not in vain!

Thanks for noticing! Should have used the search option, I guess...

There's even another one, as we broaden the connection a bit beyond his travels: Part of Xuanzang's remains were taken from Nanjing by soldiers of the Imperial Japanese Army in 1942, and are now enshrined at Yakushi-ji in Nara, Japan (wiki)

Could "Captain James Cook" under "Individual People Connections" be renamed "James Cook"? It seems weird to have his title "captain" in front of it while this is not the case with others. Just a question of being consistent.

As a counterpoint, I'd mention that in much of the English-speaking world where he traveled, he is better known as Captain Cook than as James Cook. You can see evidence of this with the number of tourist attractions with Captain Cook in their name, rather than James Cook. I'd recommend keeping the Captain in the full name of Captain James Cook for the connection.

And another one for "Individual People Connections": Giosafat Barbaro, a Venetian diplomat, merchant, explorer and travel writer

- Aleppo - After the death of Uzun Hasan in 1478, Hassan's sons fought each other for the throne. Barbaro hired an Armenian guide and escaped by way of Erzerum, Aleppo, and Beirut. He reached Venice in 1479.
- Corfu - In 1473 Barbaro traveled to Cyprus by way of Corfu, Modon, Corone and Rhodes.
- Pasargadae - Giosafat Barbaro was the first European to visit the ruins of Pasargadae, where he believed the local tradition that misidentified the tomb of Cyrus the Great as belonging to King Solomon's mother.
- Persepolis - Barbaro visited the ruins of Persepolis, which he incorrectly thought were of Jewish origin.
- Rhodes - In 1473 Barbaro traveled to Cyprus by way of Corfu, Modon, Corone and Rhodes.
- Venice and its Lagoon - Barbaro was born in Venice and was a member of the Venetian Barbaro family. He became a member of the Venetian Senate in 1431.
- Yazd - While in Persia, Barbaro visited Yazd.

For Silk Roads:
Already inscribed, still on T List: Chinese Section of the Silk Road: Land routes in Henan Province, Shaanxi Province, Gansu Province, Qinghai Province, Ningxia Hui Autonomous Region, and Xinjiang Uygur Autonomous Region; Sea Routes in Ningbo City, Zhejiang Province and Quanzhou City, Fujian Province - from Western-Han Dynasty to Qing Dynasty

Any guess if the 2 other (identical) T-list items are either an extension or new WHS?

A connection in the category "History Connections": the Nine Years' War

The Nine Years' War (1688–1697) was a conflict between France and a European coalition which mainly included the Holy Roman Empire (led by the Habsburg Monarchy), the Dutch Republic, England, Spain, Savoy and Portugal. It was fought in Europe and the surrounding seas, in North America, and in India. It is sometimes considered the first global war. (Wikipedia)

- Cartagena - The Raid on Cartagena, in April 1697 during the Nine Years' War, by Sir Bernard Desjean, Baron de Pointis and Jean Baptiste Ducasse was a severe blow to Cartagena. The Baron's forces included 22 large ships, 500 cannon, and 4000 troops, while Ducasse's forces consisted of 7 ships and 1,200 buccaneers. They quickly overwhelmed Sancho Jimeno de Orozco's force of 30 men in the San Luis de Bocachica fortification. Then, San Felipe de Barajas also fell and the city came under bombardment. The renowned Spanish defences were not what they had once been, and Pointis conquered both fortresses which defended Cartagena relatively easily, losing only sixty men. Between May 6 and 24, the French plundered the city, accumulating loot valued at ten to twenty million livres. (Wikipedia)
- Fortifications of Vauban - The naval Battle of La Hougue took place off the town in 1692. On 3 June 1692 during a heated battle with the Anglo-Dutch fleet, twelve French ships were sunk in the vicinity of the Island of Tatihou, just off the coast of Saint-Vaast-la-Hougue. It was the decisive naval battle of the Nine Years' War. Following the French defeat, two fortified towers were built from 1694 onwards on the mound at La Hougue and Tatihou Island by a student of Vauban, Benjamin de Combes, in order to defend the bay. (Wikipedia)
- Grand Place, Brussels - The bombardment of Brussels by troops of Louis XIV of France on August 13, 14 and 15, 1695 was part of the Nine Years' War. The French forces hoped that by bombarding, or threatening to bombard Brussels, they would be able to divert Allied troops from the Siege of Namur. The bombardment and the resulting fire were together the most destructive event in the entire history of Brussels. The Grand Place was destroyed, along with a third of the buildings in the city. The strategy was unsuccessful, and no military gain came of the bombardment, although Louis XIV's reputation suffered for such a barbarous act. (Wikipedia)
- Speyer Cathedral - During the Nine Years' War, the people of Speyer brought furniture and possessions into the cathedral, stacking everything several metres high hoping to save them from the French troops of Louis XIV marauding the town. But on 31 May 1689 the soldiers broke in, pillaged the imperial graves and set everything alight. On that day almost the whole town of Speyer was burned down. In the heat of the fire the western part of the nave collapsed and the late Gothic elements were destroyed. (Wikipedia)
- Upper Middle Rhine Valley – The French army captured the town of Bingen in 1688, at the beginning of the Nine Years' War. Coblenz was bombarded. Bingen was torched on 4 June 1689.

Good one! I will add it.

1. Under the connection "Works by Nobel Prize winning authors", this can be added to "Paris, Banks of the Seine":

Patrick Modiano (2014) - Un cirque passe

2. Also, under the connection "Painted by JMW Turner" in "Individual People", there should be added "Stonehenge", as Turner made several drawings and paintings of Stonehenge. (Google search + Tate 1 + Tate 2 + Article in The Guardian)

This can be added for the Abbasid Caliphate:

- Damascus - On 25 August 750, the Abbasids, having already beaten the Umayyads in the Battle of the Zab in Iraq, conquered Damascus after facing little resistance. With the heralding of the Abbasid Caliphate, Damascus became eclipsed and subordinated by Baghdad, the new Islamic capital. (Wikipedia)
