TIAA Bank Field is an American football stadium located in Jacksonville, Florida, that primarily serves as the home facility of the Jacksonville Jaguars of the National Football League (NFL). The stadium opened in 1995 as Jacksonville Municipal Stadium on the site of the old Gator Bowl Stadium (erected 1927), and included some portions of the older stadium. Located on the St. Johns River, it sits on 10 acres (4.0 ha) of land in downtown Jacksonville.

In addition to hosting the Jaguars, the stadium is also regularly used for college football, concerts, and other events. It is the regular site of the annual Florida–Georgia game, a college football rivalry game between the University of Florida and the University of Georgia. The stadium is also the home of the annual Gator Bowl, a post-season college bowl game. Additionally, the stadium hosted Super Bowl XXXIX in 2005 and is one of the venues used by the United States men's national soccer team.

From 1997 to 2006, the stadium was named Alltel Stadium after communications company Alltel purchased naming rights. The facility was renamed EverBank Field in 2010, following the approval of a five-year, naming rights deal with the financial services company EverBank. The agreement was extended in 2014 for an additional 10 years. The Jaguars announced in February 2018 the stadium would be renamed TIAA Bank Field for the 2018 NFL season after EverBank was acquired by New York-based TIAA.

Hardin Penworks, LLC, certifies that material supplied to the artisan of the accompanying hand-crafted item was sourced from the plastic seats of Williams–Brice Stadium. Home stadium for the South Carolina Gamecocks football team from the University of South Carolina in Columbia, SC, Williams–Brice Stadium is currently the 16th largest on-campus college football stadium in the NCAA.

The stadium is often called "Willy B" by Gamecock fans and local media, and the name has been commonly used by these groups since at least the early 1970s when the university held a fund-raising campaign to raise money for an AstroTurf playing surface, called "The Cockpit".

The stadium was originally built in 1934 with help of federal Works Progress Administration funds as Columbia Municipal Stadium. It was built to replace Melton Field, an aging wooden structure that was located where USC's Thomas Cooper Library stands today. In 1941, the stadium was deeded to USC and renamed Carolina Stadium until 1972 when it was renamed Williams–Brice Stadium.

This material is guaranteed to be 100% Authentic.

Yankee Stadium History

The Old Yankee Stadium: The House That Ruth Built

Yankee Stadium, the legendary "House That Ruth Built," stands as one of the most iconic venues in American sports history. Located in the Concourse section of the Bronx, New York City, the original stadium opened its doors on April 18, 1923, as the new home of Major League Baseball’s New York Yankees. Previously tenants of the New York Giants at the Polo Grounds, the Yankees’ owners, Jacob Ruppert and Tillinghast L’Hommedieu Huston, invested boldly in a state-of-the-art ballpark to capitalize on the surging popularity of their star slugger, Babe Ruth.

Construction began on May 5, 1922, on land purchased from the estate of William Waldorf Astor for around $675,000. Built by the White Construction Company at a cost of approximately $2.5 million (equivalent to roughly $36–39 million today), the stadium was completed in just 284 days. It featured a massive horseshoe-shaped design with triple-decked grandstands—the first true "stadium" in baseball rather than the wooden or steel-framed parks common at the time. Its innovative scale accommodated up to 58,000–60,000 fans—nearly double many contemporaries—reflecting confidence in Ruth’s drawing power.

On Opening Day, Ruth delivered a storybook moment, hitting the stadium’s first home run in a 4–1 victory over the Boston Red Sox. Sportswriter Fred Lieb of the New York Evening Telegram promptly dubbed it “The House That Ruth Built,” a nickname that endured for decades. The Yankees won the 1923 World Series in their inaugural season at the new park, launching a dynasty. Over its lifetime, the original Yankee Stadium hosted 6,581 regular-season Yankees games and 37 World Series contests, playing a central role in 26 of the franchise’s championships.

The stadium wasn’t just about baseball. It also served as home to the New York Giants NFL team from 1956 to 1973 and hosted major boxing matches, concerts, and other events. Its short right-field porch became legendary for Ruth and later power hitters like Mickey Mantle, Roger Maris, and Reggie Jackson. Monument Park, initially in center field and later relocated, honored the franchise’s greats and became a hallowed ground within the ballpark.

By the late 1960s and early 1970s, the aging facility showed its wear. A major renovation from late 1973 to April 1976 forced the Yankees to play at Shea Stadium (home of the Mets). The $160 million overhaul removed obstructing columns for better sightlines, added escalators, modernized concessions and restrooms, and updated the overall infrastructure, breathing new life into the venue for another three decades.

Despite the updates, structural concerns mounted in later years. A 1998 concrete collapse in the stands led to a game cancellation, highlighting ongoing maintenance challenges. The stadium closed after the 2008 season. Its final game on September 21, 2008, featured a memorable ceremony with legends and a 7–3 Yankees win over the Baltimore Orioles. Demolition began in 2009 and was completed in 2010. The site was transformed into Heritage Field, a public park preserving the spirit of the original location.

The old Yankee Stadium represented more than concrete and steel—it embodied the golden era of baseball, the rise of the Yankees as America’s team, and the cultural heartbeat of New York. Its legacy lives on in the new Yankee Stadium (opened 2009), which incorporated architectural tributes like the copper frieze and Monument Park. For generations of fans, “The House That Ruth Built” remains the Cathedral of Baseball, a symbol of excellence, history, and unforgettable moments.
