The evergreen that grows on the hospital grounds again sports 30,000 bulbs, and lighting them is one of the kickoffs for the Christmas season in San José.
But simply lighting a Christmas tree will not do. There have to be choruses, clowns and holiday music.
Sick children who can do so line the hospital balconies for the event.
This year, as is traditional, hospital outpatients, including young cancer sufferers, were invited as special guests.
The tree is stunning, and the bulbs will continue to shine into the new year, making the hospital on Paseo Colón a holiday landmark.
