Église Sainte-Hélène de Nice, Historical church in Nice, France

Église Sainte-Hélène is a Catholic church in Nice whose pale tan and peach facade bears the gold inscription "ECCLESIA SANCTAE HELENAE IN NICEA DICATA" above a dark double door and arched window. A square bell tower with a clock face, bell opening and cross rises on the left; the campanile was likely added in the second half of the 18th century.

This building originated from a chapel constructed between 1646 and 1654 following a request for daily masses at the site. In 1728, the bishop of Nice received Vatican approval to transform the chapel into a parish church.

The dedication to Saint Helena stems from Canon Honoré Rossignoli, provost of Nice Cathedral, who invoked her intercession in his will of 16 June 1646 and funded daily Masses in a chapel on his brother Jean's Carras property. The facade bears the Latin inscription "ECCLESIA SANCTAE HELENAE IN NICEA DICATA".

The church stands in the Carras district of Nice, in the Alpes-Maritimes department. Its square bell tower with a clock face and bell opening rises to the left of the facade, so the building is easy to recognise from the street. The entrance is through the dark double door beneath the arched window.

The organ was built in 1978 by the Manufacture provençale d'orgues in a German baroque style. After 32 years, Yves Cabourdin carried out its overhaul, dismantling all 1,098 pipes. The instrument is not the church's only old element: the campanile's style suggests it was added in the second half of the 18th century.
