Collegiate Church of Notre-Dame, Melun, Romanesque and Gothic church in Melun, France.

The Collegiate Church of Notre-Dame stands on rue de la Courtille on the île Saint-Étienne in Melun. Its pale grey and cream stone front has a steep gable crowned by a cross and a circular wheel-tracery window, with two square towers and tall spires to the right. The nave, aisles, transept and tower bases were built by 1031 in the Romanesque style, with square, plain pillars and small windows; the nave is 32 metres long.

King Robert II of France founded the building between 1016 and 1031 as an expression of royal power and faith. Later, it underwent major renovation and transformation under King Francis I between 1515 and 1524.

The Melun Diptych, commissioned by Étienne Chevalier, hung in the church from the mid-15th century until it was dispersed and sold around 1773, probably to fund building work. Its panels are now in Chantilly and Berlin. The church also keeps a Cavaillé-Coll organ built in 1851 for the singer Pauline Viardot, sold to the parish in 1883.

The church sits on rue de la Courtille in Melun and opens to visitors without entry fees. Guided tours are available, so you may want to check opening hours before your visit to make the most of your time.

The organ began as a salon instrument, built in 1851 by Aristide Cavaillé-Coll for Pauline Viardot's home on rue de Douai. It travelled with her to Baden-Baden in 1863 and Bougival in 1871 before she sold it to the church in 1883. A shell splinter from the Second World War pierced a carved medallion bearing her monogram; the scar was never repaired.
