There has been a church at the location of St-Eustache since the early 1200s, shortly after the market activity of Les Halles began. Today the market is gone, but the church is still considered the "market cathedral."

The present church was consecrated in 1640. It is Gothic in design but has beautiful Renaissance decor.

The importance of the market is reflected in the stained glass; one panel shows a pig and the words "corporation charcuterie." Perhaps the most notable reference is the sculpture, The departure of the fruit and vegatable market from the heart of Paris, 28th February 1969. Located in one of the side chapels, this poignant and humorous sculpture reminds us of the importance of Les Halles to the church and vice versa.

Its organ is considered one of the best and biggest in Paris. In 1855, Hector Berlioz conducted the première of his Te Deum at St-Eustache, along with 950 musicians. Today, church services and weekly organ recitals allow one to appreciate this beautiful instrument.

St-Eustache has hosted its share of celebrity events, including:
- Baptisms of Richelieu, Molière, and Madame de Pompadour
- First communion of Louis XIV
- Funerals of La Fontaine, Mirabeau, and Mozart's mother

Located near the Rue Montorgueil, in the midst of the modern Les Halles shopping center, and just steps from famous landmarks like Au Pied du Cochon, where market workers would retire for a late night/early morning bowl of onion soup, St-Eustache remains the center of this lively neighborhood.
