The altar is believed to have originally contained a statue of Our Lady of the Angels, but in modern times contains a Holy Cross. There is a statue of Joan of Arc which was donated to the church in 1919 by the then-mayor of Puducherry, Francois Gaudart. The twin towers have stained glass windows that playoff red, blue, and yellow. The original chapel was painted white both inside and out, hence the name White Chapel. A special mixture of paint, egg, and limestone was used to paint the walls. The exterior color was changed in the 1900s and the interior color in the 2000s. The temple bells are believed to have been brought from France. The bell had a complex mechanism where pulleys and ropes were attached to a rope at the bottom. In 2012, following the renovation of the chapel, the operation of the bell was suspended due to vibrational effects causing disturbance to neighbor structures. The temple is locally called Dumas Church as it is located on Dumas Street in White Town.
