The Great Organ of the St. Stephen Basilica: The organ was built by organ-builder master József Angster in 1905.
The instrument was triple-banked and pedalled at that time, with 64 registers, a free combination of 6 key sets, pneumatic control and bag-chests. In 1932, however, it was completed to 4 manuals and the number of versions was increased, then it was rebuilt by the Rieger Organ Factory with verisons up to 79 in 1937.
The latest works of refashioning were in progress from 1992 to 2004. Works done by the Váradi és fia Organ Building Company of Budapest, a new, movable computer-controlled console was added with an electric stracture and the wind-chests were renewed in a conical chest system.
By now, its registers have numbered as many as 93 and the Chamade sticking horizontally out of the front has added special interest to it. With the free combinations numbering 1152, the organ has 22 reeds instead of the original 9 ones.
Its reed-pipes number 7544, the biggest one being 105 meters, the shortest one 5 millimetres in lenght, and the air supply is guaranteed by 3 high-powered, electric fans. On the design by József Kauser, the organ-chest was manufactured in the Thék Endre Furniture Factory. While renewing it for the last time, it was overlaid with a leaf gilding of 22-carat gold.
The new Eucharist-Chapel of St. Stephen's Basilica: The new Eucharist-Chapel of the church was consecrated by Archbishop of Péter Erdő in the course of the Corpus Christi mass on June 6, 2010. The liturgical room formed in the place of the earlier treasury is to be found right of the portal, at the bottom of the southern tower. The 5 meter wide and 7 meter high interior of an octagonal plan is split into two by an enmarbled, gilded quotation from the Gospel : "Take this and eat it, all of you; this is my body which is given for you. Take this and drink from it, all of you; this is the cup of my blood, the blood of the new and everlasting covenant. This blood is to be shed for you and for many, for the remission of sins. Whenever you do this, you will do it in memory of me."
The lower space covered with Carrara marble, refers to a sacred tradition with its usual attributes (such as sanctuary lamps, a statue of the Virgin in Gothic style) while the upper level is destined for helping the faithful to become immersed in prayer with the use of 21th century means (such as the stained glass with computer-controlled led light painting the air with the day's litrugical colour). The space has been designed by painter Norbert Bukta while the gilded "Creator's hand" in the tabernacle is a work of art by the sculptor Nobert Kotormán.
