Our Lady of the Lake Church
Mandeville, St. Tammany Parish, Louisiana
Marker Inscription
Our Lady of the Lake Church. Early in the eighteenth century, Catholic missionaries evangelized Choctaw, Chinchuba and other Indian tribes and sub-tribes on the Northern shore of Lake Pontchartrain. Among pioneer priests was Fr. Michael Baudouin, S.J., superior of the Jesuit mission in Louisiana and Vicar-General to the Bishop of Quebec, Canada. Fr. J. Outendrick was the first resident pastor when the Mandeville congregation was organized in 1850. Fr. Adrien E. Rouquette, "Chahta-Ima," also labored here and elsewhere in St. Tammany civil parish. The present church was dedicated in 1953 during the pastorate of Fr. Canisius Bluemel, O.S.B., one of several Benedictines serving here since 1890.

The Story
Catholic missionaries reached the north shore of Lake Pontchartrain early in the eighteenth century, evangelizing the Choctaw, Chinchuba, and other peoples; among the pioneers was Fr. Michael Baudouin, superior of Louisiana's Jesuit mission. A resident congregation was organized at Mandeville in 1850, and the missionary-poet Adrien Rouquette, 'Chahta-Ima,' also labored here. The present Our Lady of the Lake church was dedicated in 1953 under Benedictine care.
Why it matters
It traces a continuous line of missionary presence in Louisiana from the colonial French era through the twentieth century, and its early contact with Native peoples.
The story behind this marker
AI contextThe era
To stand on the north shore of Lake Pontchartrain in the early 1700s was to stand at the far edge of a French empire that reached from the St. Lawrence to the Gulf. Louisiana was a young colony, thinly settled and wrapped in pine forest and cypress swamp, and the great brackish lake was less a barrier than a highway — the quickest way between scattered settlements was by boat across the water.
Spiritually, this whole world answered to a bishop very far away. In the French colonial period the church in Louisiana fell under the Diocese of Quebec, in Canada, and priests here worked as that distant bishop's agents on the ground. The marker's own reference to a Vicar-General to the Bishop of Quebec is a small window onto how vast and improvised the colonial church really was.
The people already living along this shore were Choctaw and smaller allied and neighboring groups. Into their country came Catholic missionaries — often Jesuits, the era's great order of frontier evangelists — who traveled light, learned languages, and built their missions where the people were rather than where a town happened to sit.
People & events
The earliest name the marker preserves is Father Michael Baudouin, a Jesuit who served as superior of the order's Louisiana mission and, remarkably for a working frontier priest, as Vicar-General to the Bishop of Quebec. That he ministered among the Choctaw, Chinchuba, and other peoples of this shore tells you how the colonial church operated: its senior figures were not desk-bound administrators but men who paddled to the missions themselves.
More than a century later, in 1850, the scattered faithful around Mandeville were finally gathered into a formal congregation, with Father J. Outendrick as their first resident pastor. The word "resident" matters — it marks the moment this became a settled parish with its own priest rather than a stop on a missionary's long circuit.
The figure who most captures the imagination is Father Adrien Rouquette, remembered by the Choctaw name "Chahta-Ima." A Louisiana-born poet who became a priest, he gave himself over to ministry among the Choctaw of St. Tammany, and the name he carried signals how completely he cast his lot with them. The present church was dedicated in 1953 under Father Canisius Bluemel, one of a line of Benedictine monks who have served here since 1890 — the newest chapter in a very old story.
Its place in the American story
This single church knots together strands of the American story that we usually keep in separate boxes. It reaches back into the French colonial era, when much of the interior of the continent was Catholic and French-speaking rather than English and Protestant — a reminder that the United States grew up alongside, and eventually absorbed, other European colonial worlds.
It also records the long, complicated encounter between missionaries and Native peoples. The Choctaw and their neighbors were not a backdrop to this history; they were the reason the earliest priests came to this shore at all. A poet-priest who took a Choctaw name is a striking emblem of how intertwined, and how unequal, that encounter could be.
Few places let you trace an unbroken thread from colonial Jesuits through a mid-nineteenth-century immigrant-era parish to twentieth-century Benedictine monks. That continuity — Jesuit, diocesan, Benedictine, across more than two centuries — is itself the point the marker is quietly making.
If you visit
Mandeville today is a leafy lakefront town, and the church you'll find was dedicated in 1953 — so don't come looking for a colonial ruin. Come instead to feel the depth of time layered under an ordinary parish. The building is modern; the story beneath it is not.
Stand for a moment facing Lake Pontchartrain and picture the water as the road it once was, carrying missionaries across from the south shore long before there were bridges or highways. That geography is the whole reason a mission took root here.
If you're building a road trip through the north shore's small towns, let this be the stop where you slow down and think about who was here first — the Choctaw and their neighbors — and about the poet who took their name. It pairs naturally with a lakefront walk, and it rewards a visitor who is willing to read a plaque slowly and let two and a half centuries settle in.

Pottery Hill
Mandeville, LA
Pottery Hill, shaded by the ancient Castain Oak, holds layered evidence of human life reaching back to the late Tchefuncte era around 800 BC and the early Marksville period of the first centuries AD. Pottery shards, bone, and shell deposits show that Native peoples — including the Acolapissa and later the Choctaw — used this ground continuously into the 20th century. Colonial settlers later prized its fine clay, running commercial potteries here until the 1940s.
Abita Springs
Abita Springs, LA
Abita Springs grew up around an old Choctaw village that took its name from the medicinal springs prized in the area. The site included the Choctaw people's last burial and execution grounds nearby, used until about 1880. The springs later drew health-seekers, but their reputation began with the Native community that lived here.
Adrien Rouquette
St. Tammany Parish, LA
Abbé Adrien Rouquette (1813–1887) was a New Orleans poet who became a Catholic priest and spent his last decades as a missionary among the Choctaw of the Bayou Lacombe region, from 1859 until his death. He lived so closely among them that they called him 'Chata Ima' — 'like a Choctaw.' His life bridged the literary world of the city and the Native communities of the north shore.
Chartier Concession
New Orleans, LA
In 1719, in the earliest years of French Louisiana, the colony's attorney general Pierre Chartier de Baulne secured the first land grant along Chapitoulas Road, at the former village of the Colapissa people. His family were among the first colonists to settle the area that would grow into greater New Orleans. The concession marks where European agriculture began overwriting an Indigenous landscape.
