Question: How tall is this monument in St. Louis built after the Apotheosis of St. Louis, which became an international symbol for the city?

The Gateway Arch is a 630 ft monument in St. Louis in the U.S. state of Missouri.  Clad in stainless steel and built in the form of an inverted, weighted catenary arch, it is the world's tallest arch, the tallest man-made monument in the Western Hemisphere, and Missouri's tallest accessible building.  Built as a monument to the westward expansion of the United States, and officially dedicated to "the American people," it is the centerpiece of the Jefferson National Expansion Memorial and has become an internationally recognized symbol of St. Louis, as well as a popular tourist destination. <SEP> Apotheosis of St. Louis is a statue of King Louis IX of France, namesake of St. Louis, Missouri, located in front of the Saint Louis Art Museum in Forest Park.  It has served in the iconography of St. Louis for more than a century.  Prior to the completion of the Gateway Arch, the statue was the principal symbol of the city. <SEP> The St. Louis Cardinals, a professional baseball franchise based in St. Louis, Missouri, compete in the National League (NL) of Major League Baseball (MLB).  As the game of baseball garnered interest in the United States in the 19th century, professional baseball in St. Louis became rooted chiefly in one disestablished Major League club – named the Brown Stockings, the same as the Cardinals' earliest name – which is loosely connected, but does not fall within the scope of, today's Cardinals.  The Brown Stockings became St. Louis' first fully professional baseball club when they gained accession in the National Association (NA) in 1875.  However, the NA folded after that season.  That winter, with five other former NA teams, St. Louis established a new, eight-team league called the National League (NL) and began play the next season.  Despite early success, Brown Stocking players were found to be connected to game fixing scandals, which forced bankruptcy and the club's expulsion from the NL.  This scandal also abrogated their professional status but some members maintained play as a semi-professional team, primarily operated by outfielder Ned Cuthbert, until 1881. <SEP> T.R.
