Saint Louis Hospital has been the prominent healthcare facility of Catholics in Thailand.

Some of the services include the Death Talk, conducting mass, or other religious ceremonies up to the patient's wills.

[5] John Paul II Charity Clinic (Thai: คลินิกจิตกุศล ยอห์น ปอล) is the hospital's charity clinic which provides basic healthcare free-of-charge for patients in poverty, poor church-goers, and the hospital's staff members.

The clinic was founded in order to commemorate the Papal visit to the hospital of Pope John Paul II in 1984.

Founded in 1982, the chapel is now occupied by Deutschsprachige Kath: Gemeinde St. Marien in Bangkok, Thailand.
