Open Image ModalBARCELONA, SPAIN - OCTOBER 26: People enjoy the view over the city with 'La Sagrada Familia' in the background on October 26, 2015 in Barcelona, Spain. 'La Sagrada Familia' Foundation announced on October 21 that the temple has entered final construction phase. The first stone was laid on March 19, 1882 following the Neo-gothic design drawn up by the architect Francisco de Paula del Villar y Lozano, the first architect of the 'Sagrada Familia'. Antoni Gaudi took over the design of the Sagrada Familia in 1883 until his death on June 10, 1926 due to a traffic accident. The main projects being undertaken over the coming years are the construction of the west sacristy, the central towers and the Tower of Jesus which will eventually be crowned with a cross 170 metres above the ground level. According to 'La Sagrada Familia' Foundation, the temple could be finished in the first third of the 21st century. More than 3 million people visit the temple each year.
