The home of the Red Sox opened in early 1912, and that makes it the oldest ballpark in all of Major League Baseball.

The arena, which seats just over 37,000, is also one of MLB's smallest.

But that's part of the charm that's made Fenway an icon not just for Boston, but for sports in general.

The 52-story, 749-foot skyscraper was completed in 1964, and is New England's second-tallest building.

Boxy and somewhat nondescript, the Charles Luckman & Associates design has its critics; but the tower unmistakable against the city's skyline, and it ushered in Boston’s so-called High Spine of skyscrapers.

Modern giant (and possible Nazi spy) Philip Johnson was the architectural force behind this wing of the Boston Public Library's central branch. It opened in December 1972.

Even at 10 levels, it harmonizes height-wise with the older McKim Building on Copley Square.

Henry Hobson Richardson designed this iteration of the Episcopal church, which was completed in the late 1870s (the parish dates from 1733).

Other municipal buildings locally and nationwide have imitated its Romanesque style.

The tower formerly known as the John Hancock is New England's tallest building at 790 feet, a distinction it has held since the Henry Cobb-designed spire was finished in 1976.

It's often the first thing one sees from a distance when approaching Boston on the ground.

Charles Bulfinch designed the State House, which was finished in early 1798 and built on a cow pasture John Hancock once owned.

Wood shingles originally comprised its famous dome. Those gave way to copper and then to a 23-karat gold coating (which looks neat, yes, but was also practical: to prevent leaks).

Inside also happens to be one of the Boston area’s most beautiful building interiors.

The monument commemorates the first major battle of the Revolutionary War on June 17, 1775.

Solomon Willard designed the 221-foot obelisk, which dates from 1842. Its interior is open most days for climbing.

The brutalist creation has been an architectural punching bag since its completion in 1968, though it seems to finally be getting some positive recognition of late.

Gerhard Kallmann and Michael McKinnell, then professors at Columbia, won an international competition to design the civic hub.

They chose to pivot from more traditional city-hall fare as well as from sleek glassiness to a modern design that still perplexes the masses—but that also, in its way, reflects Boston’s desire to be different and bold.

Shepley, Rutan and Coolidge designed the Classical revival structure in the late 1890s. 

South Station, of course, serves as the busiest train and bus hub in New England. 

The building dates from the early 1720s and is Boston's oldest church.

What makes it iconic, though, is that it was from its 191-foot steeple that Paul Revere learned the British were coming by sea, not land.

Robert Newman, the church's sexton, provided Revere the two-lantern signal.

The 496-foot Neoclassical building, built in stages from the 1830s through the early 1910s, was once the tallest spire in Boston (until the Pru surpassed it in 1964).

It is currently an extended-stay Marriott—and still includes one of the most beautiful building interiors in the Boston area.

I.M. Pei designed the Columbia Point library and museum, which is a repository for all things JFK-related, including a permanent exhibit on his family.

The complex opened in 1979 and was rededicated in 1993.

The starkly geometric design made Pei's reputation; and the building is probably the most famous in Boston south of Columbus Avenue.
