Francesc Daniel Molina i Casamajó (Vic, 1812–Barcelona, 5 July 1867) was a Spanish architect.^[1]

He was born in the city of Vic, Barcelona Province, in 1812. He completed his early studies at Escola de la Llotja,^{[note 1]} an art and design school in Barcelona.^[2] In 1843, he graduated from the Real Academia de Bellas Artes de San Fernando^{[note 2]} in Madrid.^[3][4] And then, in 1850, he was elected fellow of the Reial Acadèmia Catalana de Belles Arts de Sant Jordi.^{[note 3][5]}

In 1851, he designed the Plaça del Duc de Medinaceli^{[note 4]} square in Barcelona.^[6] The following year, he built the Santuari de la Mare de Déu de la Misericòrdia [ca]^{[note 5]} church in the municipality of Canet de Mar.^[7]

Furthermore, in 1852, he was commissioned to design a monument to the memory of Minister of War Francisco Bernaldo de Quirós [es], Marquis of Campo Sagrado [es]. The monument was completed in 1856 and it is known as the Font del Geni Català [ca],^{[note 6]} a historic fountain built in the neoclassical style and located in the Pla de Palau [es]^{[note 7]} square in Barcelona.^[1][8]

But Molina's most important project was that of the Royal Square in Barcelona (1848–1859). It is considered the traditional Spanish main square, with its Elizabethan-style façades and arcaded ground floor, in the same style as the façade of the Teatre Principal,^{[note 8]} after his restoration following a fire in 1845.^[1][8]

He served as the council architect of Barcelona in 1855,^[3] succeeding Josep Mas i Vila [ca]. He worked on the coat of arms on the pediment of the neo-Gothic façade of Barcelona City Hall, as well as the Saló de la Reina Regent,^{[note 9][note 10][9]} which was finished in 1860. In 1865, influenced by The Cerdá Plan for Barcelona, he drafted an urban renewal plan for Sabadell, but it fell through.^[10]
