The Primatial Basilica of the Assumption of the Blessed Virgin Mary and St Adalbert (), also known as the Basilica of Esztergom (), is an ecclesiastic basilica in Esztergom, Hungary, the mother church of the Archdiocese of Esztergom-Budapest, and the seat of the Catholic Church in Hungary. It is dedicated to the Assumption of Saint Mary and Saint Adalbert.
It is the largest church in Hungary. Its inner area is 5,600 m<sup>2</sup>. It is 118 m long and 49 m wide. It has a reverberation time of more than 9 seconds. Its dome, forming a semi-sphere, is situated in the middle, and it has 12 windows. It is 71.5 m high inside (which makes it one of the tallest domes in the world), with a diameter of 33.5 metres, and is 100 m high from outside, the stairs count 400 steps counted from the crypt.
The huge crypt, built in Old Egyptian style in 1831, is today the resting place of late archbishops, among others, József Mindszenty, famous for his opposition to both Nazi and Communist rule.
History
The present church is built on Castle Hill on the foundation of several earlier churches. The first of these, the Saint Adalbert church, was built by Stephen I of Hungary between 1001 and 1010 to serve as Hungary's first cathedral. It was rebuilt after being burned down in 1180, subsequently surviving the
First and Second Mongol invasion of Hungary. However, in 1304, Wenceslaus III, a probable candidate for the Hungarian throne, sacked the castle and the church. It was repaired in the following years. The archbishops of the 14th and 15th century made the church more ornate and added a huge library, the second most significant one in the country. In 1543, following its capture by the Ottomans during a series of wars with the Habsburg monarchy, the cathedral's sanctuary was demolished and the remainder of the building used as a mosque.
In 1820, the Archdiocese was restored and archbishop Sándor Rudnay decided to restore Esztergom's status as mother church of the country. The foundation stone of today's cathedral was laid on April 23, 1822, on the feast of St. Adalbert.
Under archbishop János Scitovszky, the upper church was completed and dedicated on August 31, 1856 in the presence of Emperor Franz Joseph. The 1856 consecration ceremonies featured the premiere of the Missa solennis zur Einweihung der Basilika in Gran (Gran Mass), composed and conducted by Franz Liszt, and featuring the organist Alexander Winterberger. The piece had been commissioned by the Archbishop.
During World War II the colonnade and the cupola were damaged by bombing.

The architect was Pál Kühnel and the lead contractor was his nephew, János Packh. Because of the topography, main facade faces east. The foundation-stone was laid and work began in 1822. After Packh's murder in 1839, József Hild was placed in charge of construction. In 1846, the cross was placed on the dome. Hild completed the building in Classicist style in 1869.
Interior
The altarpiece (13.5 × 6.6 metres) by Girolamo Michelangelo Grigoletti, depicts the Assumption of the Blessed Virgin Mary. It was commissioned by Archbishop József Kopácsy.
The Cathedral Treasury is on the first floor. It opened in 1886 with the aim of preserving and displaying the liturgical instruments once used in the cathedral. It contains the "Matthias' Calvary", a 15th-century golden cross for coronation oath from the Árpád era. Pope John Paul II used the Suki chalice for the Holy Mass, when he visited Esztergom in 1991.
The basilica is also known for Bakócz Chapel (named after Tamás Bakócz), built by Italian masters between 1506–1507 out of red marble of Süttő, its walls adorned with Tuscan Renaissance motifs. In 1823, the chapel was carefully disassembled (into about 1,600 pieces) and moved 20 metres away from its original location and attached to the new basilica.
