The construction style of the basilica is inspired by semi-gothic architecture. The façade of the Basilica is 67 ½ feet in width which gives a beautiful and a wide look to the structure. Due to the strong rooted foundation made up of rock the structure of the Basilica is very strong and unshakable. The foundations are further supported by buttresses. 

The Façade: The façade of the church is made up of four horizontal floors. The lowest floor contains the main entrance and has two side windows. There are two protective gothic stone arches, supported by elegant round stone columns made of Malad stone, to protect the wooden panels of the main entrance from the rains and extreme weather conditions.

The construction style of the basilica is inspired by semi-gothic architecture. The façade of the Basilica is 67 ½ feet in width which gives a beautiful and a wide look to the structure. Due to the strong rooted foundation made up of rock the structure of the Basilica is very strong and unshakable. The foundations are further supported by buttresses. 

The Façade: The façade of the church is made up of four horizontal floors. The lowest floor contains the main entrance and has two side windows. There are two protective gothic stone arches, supported by elegant round stone columns made of Malad stone, to protect the wooden panels of the main entrance from the rains and extreme weather conditions. These also help enhance the beauty of the entrance.

The first floor has five windows, two of which are embodied in the towers and three are used for providing ventilation to the nave. The main portal has an arch on which there is the emblem of the Basilica, AM, which stands for AVE MARIA. It is the initial letters of the greeting given by Angel Gabriel to Mary at the time of the Annunciation. The letters are mounted on a crown and their beauty is enhanced by two stems of lilies, which are symbols of Mary being a queen, full of innocence and virginal purity.

The third floor has four windows and a prominent circle which is engraved with the words ANNO JUBILAEI 1904, indicating the golden jubilee year of the promulgation of the Dogma of the Immaculate Conception and also marks the year of the inauguration of this new Basilica. The cross is placed at the central triangular elevation of this pointed façade.

The fourth floor has the pyramidal spires on both the sides with the cross that rises high in the sky.

The Twin Towers: The twin towers have foundations of 18 ¼ feet in length and stretch up to a total height of 98 feet. The towers have two entrance doors and staircases which leads to the octagonal steeple. The steeples and their cornices have been made of Porbunder slabs and stones respectively, and it is crowned with a Cross. A bell, which is 24’’ at the rim, is placed in the northern tower with an engraved cross and the inscription: AVE MARIA, NOSSA SENHORA de MONTE, BANDORA 1852. The other bell, which is 18’’ at the rim, is placed in southern tower. It sounds heavenly when both are rung at the same time.

Standing erect on each corner of the two towers is a stone pillar with Corinthian capitals. These eight pillars are there to inspire devotees/visitors to be able to stand erect and think of high and noble things for themselves and for mankind.

The Nave: The shell of the nave has been constructed by using stone, and it is 66.9’ long and 38’ broad. Apart from the main entrance, there are four side entrances, and above each of these doors there is a large window which allows light to enter the nave.

The height of the ceiling of the nave is 42 feet and it is made of teak wood. On the first floor, it is supported by a three-sided wooden loft. It rests on either side on four teak wood columns which have fluted shafts and Corinthian capitals. The base of the column is made of strong stones. The columns support the weight of the loft as well as the wooden ceiling. On the west side there is an additional choir loft on the second floor. The entire wooden ceiling is topped with a roof which in turn is covered with Mangalore tiles.

The Sanctuary: The Sanctuary of the Basilica is made to be separate from the Nave by two stone arches, two elevations of the floor, and steps. Three round stone columns support the outer arch while only two such column support the inner arch.

The Side Altars: There are two side altars which are situated outside the first arch. The altar which is to the South is dedicated to St Joseph, while the one on the North is dedicated to the Sacred Heart of Jesus. The latter was declared sacred by the late Cardinal Valerian Gracias on the occasion of the Consecration of the Shrine on 8th of November 1954.

The Projections: Beside the area of the side altars there are projections on both sides. The southern projection is part of the sacristy where priest prepares for the service. The projection on the northern side, which was earlier a side chapel for private masses, now serves at the Eucharistic chapel. As seen from outside, this projection has letters IHS which are encircled by a crown of thorns that are mounted on the outer side of the rear wall. These stand for the three letters of the Greek word which is used to spell the name of Jesus (IHSous).

The Altar: The high altar has a marble pulpit which is 4 feet in height and has 7 steps leading up to it. Many liturgical symbols are engraved on the outer body of the pulpit, such as bread loaves, fish, the two tablets of the Ten Commandments, IHS and PX which are the symbols of Christ, etc. There is a large Crucifix above the pulpit, which is an object of reverence for devotees and visitors. One can see Mary’s prophetic words right above the pulpit. These words form the sentence which reads as “All generations shall call me blessed”. The letters have been made out of wood and are painted in gold. The words are placed on a prominent place on top of the semi-circular stone arch which separates the nave from the sanctuary. The words are crowned by a fiberglass mural portraying Our Lady as the Queen of Heaven and of all Saints.

Just below the arch, on both the sides, there are the court of arms of the Pope and also of the Bishop of Bombay.
