Ifs de La Haye-de-Routot, Ancient yew trees in La Haye-de-Routot, France.

The Ifs de La Haye-de-Routot are two common yew trees in the cemetery of Notre-Dame church in the village centre. Each trunk exceeds 10 metres in circumference and is hollow at the base. The eastern yew holds a chapel dedicated to Sainte-Anne; the western yew holds an oratory dedicated to Notre-Dame-de-Lourdes.

The age of the two yews is estimated at around 1,000 years, though figures of 1,400 and 1,600 years have been proposed without certainty. In 1866 a chapel to Sainte-Anne was installed in the eastern trunk; the Notre-Dame-de-Lourdes oratory followed in the western yew in 1897. Both trees were classed as a Site inscrit in 1932 and labelled "arbre remarquable de France" in 2001.

The hollow of the western yew holds the Notre-Dame-de-Lourdes oratory, installed in 1897 and still used: its grotto-like cavity is dotted with candles. The Sainte-Anne chapel in the eastern yew, installed in 1866, no longer hosts worship. On the evening of 16 July, a charity confraternity founded in 1496 lights the large Saint-Clair fire, and the trees are linked to plant festivals such as the "fête des légumes oubliés" and "Orties folles".

Both trees are easily accessible in the village center next to the church, making them simple to visit on foot. The western yew contains an active prayer space where candles are regularly lit by visitors.

The hollow trunks of these thousand-year-old trees were originally just natural cavities, but were later deliberately converted into dedicated religious spaces. What began as simple interior spaces has become a functioning chapel and oratory where visitors still pray today.
