The reason for its being called celestial was due to the fact that the chapel belonged to the Chorão Seminary, where spiritual things[clarification needed] were taught.

The inmates of the Chorão Seminary in the evenings spent their time here enjoying rest and fresh air.

[4] In 1959 at the request of the then vicar of Our Lady of Grace Church (Chorão Island) Fr Tome Caetano de Nazare, the Dept of Public Works effected many improvements.

The interior wall, the columns and the flooring of the circular corridor were plastered with cement.

Besides in the interior of the chapel itself, the ceiling vault as well as the candle sticks and the panels on the altar were painted.
