In the fourteenth year of the Chongzhen era (1641), he was finally buried in the southwest corner of Gaochang Township, Shanghai County, Songjiang Prefecture.

[3] Xu Guangqi, a native of Shanghai County, Songjiang Prefecture, Nanzhili, in the late Ming dynasty, passed the imperial examination in the 32nd year of the Wanli era (1604) and held the highest official position as the Director of the Ministry of Rites and concurrently the Grand Secretary of the Hall of Literary Profundity.

[5] He presented several astronomical and mathematical works to the Ming Emperor, along with contributions in military strategy, salt administration, land reclamation, and hydraulic engineering.

[6] Xu Guangqi's significant contributions to east–west cultural exchange earned him the title "the first person in China to truly open his eyes to the world",[7] as described by Professor Mao Peiqi.

[8] A special guard was dispatched by the Ming government to escort Xu Guangqi's remains back to Shanghai, arriving in his hometown in the second month of the seventh year of the Chongzhen era (1634).

[10]: 65 Originally covering more than 20 mu, Xu Guangqi's tomb had two huabiao (ornamental columns) in front of it, as well as a stone archway.

Inscriptions in Chinese and Latin on the base of the cross describe Xu Guangqi's achievements,[9]: 71  and the tomb was renovated simultaneously.

In 1933, to commemorate the 300th anniversary of Xu Guangqi's passing, different communities raised funds to build an iron fence around the cross, as well as stone railings and cement roads around the cemetery.

[12] After the War of Resistance Against Japan, the trees in the vicinity were heavily felled, the soil was excavated, and the cemetery was turned into vegetable fields.

[18] The main tomb houses Xu Guangqi and his wife, Madam Wu, while his four grandsons and their wives are buried on both sides.

[2] On 13 January 1988, the tomb of Xu Guangqi was announced by the State Council as one of the third batch of nationally major protected cultural relics.

It features four exhibition themes, displaying valuable materials such as portraits, manuscripts, and documents related to Xu Guangqi.

Based on the Latin content of the epitaph on the tombstone, it was inferred that Xu Guangqi had indeed converted to Catholicism and had taken the baptismal name "Paul".
