St. Louis Arch
Here's a few I took of the St. Louis Arch over Valentine's Day weekend. After taking these I did a little reading about the arch itself and was fascinated by this (from Wikipedia) -
"The base of each leg at ground level had an engineering tolerance of one sixty-fourth of an inch or the two legs would not meet at the top. During construction, both legs were built up simultaneously. When the time came to connect both legs together at the apex, thermal expansion of the sunward facing south leg prevented it from aligning precisely with the north leg. This alignment problem was solved when the Saint Louis City Fire Department sprayed the south leg with water from firehoses until it had cooled to the point where it aligned with the north leg."
