Trinity Church

Stand on the open stone of Copley Square for a moment and listen. Traffic hums along Boylston Street. Pigeons scatter across the paving. Then look up at the heavy, warm-coloured mass in front of you. Rough granite blocks, the colour of weathered honey, are set with bands of reddish-brown sandstone. The whole building seems to sit low and solid, like something that grew out of the ground rather than something placed on it. This is Trinity Church, and it changed the way Americans thought a building could look.

Trinity is an Episcopal parish, and its congregation is older than this building. The parish once worshipped in a church on Summer Street, in what is now Downtown Boston. In 1872, the Great Boston Fire swept through that district and destroyed the old church along with dozens of city blocks. The congregation needed a new home. They chose a site here, in the Back Bay, a neighbourhood that was still being created.

And that word, created, is the first surprise. The ground under your feet was once a tidal marsh and mudflat along the Charles River. Through the nineteenth century, Boston filled it in with gravel and earth to make new land. That meant a stone church this heavy could not simply rest on the surface. Instead, it stands on thousands of wooden piles, driven deep into the soft fill. Those timbers must stay wet to avoid rotting, so the groundwater level around the church is still watched carefully today.

The architect was Henry Hobson Richardson. He was a young man from Louisiana who had trained in Paris, and Trinity was the commission that made his name. The church was consecrated in 1877. Richardson took ideas from Romanesque architecture — the round-arched, heavy-walled style of medieval Europe, before the pointed Gothic arch took over. He made that style bolder and more muscular. The result became known as Richardsonian Romanesque, one of very few architectural styles named after an American.

Look at the great central tower. It is the heart of the whole design. Richardson drew inspiration for it from a medieval cathedral in Salamanca, in Spain. The tower is square and broad, with a steep roof and small round turrets at its corners. Everything else in the building gathers around it. The roof lines step down from the tower in every direction, so the church reads as one large, connected shape rather than a row of separate parts.

Now walk slowly along the outside walls and let your eyes follow the stone. Notice the two colours working together. The rough, rusticated granite gives the walls their weight. The smoother sandstone frames the arches, the windows, and the horizontal bands. Up close, you can see the tool marks and the uneven faces of the blocks. Richardson wanted the surface to feel handmade and textured, so it catches shadow differently through the day.

The deep porch at the western front, facing the square, came a little later. It was completed after Richardson's death, by the firm that carried on his work. Its carved arches and columns are richer and more detailed than much of the original building. Take a moment under those arches. The carving includes figures and foliage, and it rewards a slow look. Many visitors walk straight through without lifting their heads.

Inside, the change is dramatic. The light drops, and the colour rises. Where the exterior is stone and earth tones, the interior glows with deep reds, greens, blues, and gold. Almost every surface is painted. This decoration was led by the artist John La Farge, who covered the walls and the inside of the tower with murals and patterns. Among the young artists who worked with him was Augustus Saint-Gaudens, later one of America's best-known sculptors.

Here is the second surprise. Trinity is often described as one of the first American churches where architect, painters, and craftsmen worked together on a single, unified interior. At the time, most American churches were plain, or decorated piece by piece. Here, the walls, the ceiling, the windows, and the woodwork were meant to be read as one work of art. Stand under the crossing and look straight up into the tower. The painted space rises above you like a coloured lantern.

The stained glass deserves its own visit. La Farge experimented with a new kind of opalescent glass, which is milky and layered rather than flat and clear. It holds colour in a soft, glowing way, almost like stone lit from within. His windows sit alongside glass made in England by the workshop of William Morris, to designs by Edward Burne-Jones. Compare them as you walk. The English windows use crisp lines and painted detail, while La Farge's glass relies on the material itself.

One name returns again and again at Trinity: Phillips Brooks. He was the rector, the senior priest, when this church was built, and he was a famous preacher in his day. Many people today know his words without knowing his name. He wrote the Christmas carol O Little Town of Bethlehem. Outside, on the side of the church, a statue honours him, with a figure of Christ standing behind him. The memorial was begun by Saint-Gaudens, the same sculptor who once painted inside these walls.

Now step back out to the square and turn toward the tall glass tower beside the church. It is the building long known as the John Hancock Tower, finished in the 1970s. Its mirrored skin holds a reflection of Trinity, stone against sky, old against new. Its construction caused damage to the church, and a long legal dispute followed. Today, that pairing of glass and granite is one of the most photographed views in Boston. Across the square, the Boston Public Library completes the scene.

Before you go, find a spot where you can see the whole church at once. Notice how the tower anchors the square, and how the stone looks warmer as the light moves across it. Think of the marsh that once lay here, and the timbers still standing in water below you. When you walk away along Boylston Street, glance back once. That low, heavy outline is the building that taught a generation of American architects how stone could feel.
