In 2000 the vaults of the central nave and the transept were built and work began on the foundations of the Glory façade. That year, on the occasion of the new millennium, a mass was held inside the church which provided an opportunity to grasp the grandiosity of the work.
In 2001 the central window of the Passion façade was completed with the installation of a stained glass window dedicated to the resurrection, the work of Joan Vila-Grau. The four columns of the centre of the crossing were also finished.
The figure and work of Gaudí were especially remembered in 2002, when Barcelona Council promoted International Gaudí Year on the occasion of the 150th anniversary of his birth. La Sagrada Família took part with different events, such as the restoration, removal and opening of the Sagrada Família Temporary Schools as a new exhibition space, or the "Night of Light and Fire", a show held on 1 June which, with its special illumination and a spectacular castle of fireworks, was the highlight of the commemoration.
In 2002, the sculptor Josep Maria Subirachs did the project for the wall of the prophets and patriarchs which Gaudí located in the porch of the Passion façade, and in 2005 the sculpture of the Ascension was placed between the towers of the façade. At the same time, the eucharistic symbols of bread and wine were placed on the windows of the central nave, the work of the Japanese sculptor Etsuro Sotoo.
In 2006 the Glory façade choir was built according to Gaudí's models. The vaults of the ambulatory of the apse were finished in 2008. Between 2008 and 2010 the vaults of the crossing and the apse are scheduled for completion; on them the tower of the central lantern crowned by a cross 170 m high will be erected, and the apse tower, dedicated to the Virgin Mary. The central tower will be surrounded by four others, dedicated to the evangelists. The church will be complemented with the construction of the main façade, the Glory façade.
