The station was opened by the Metropolitan Railway in 1876 as an extension to the East from it's original terminus at 
Farringdon [1]. Building the extension had been difficult which caused some delays in opening it [2]. The line was extended South to 
Tower Hill in 1882 completing the Circle Line (though this did not become a separate line officially until 1949).
Aldgate is made up of a triangle of lines with two island platforms. The two outer platforms have through lines for the Circle Line and the two inner platforms form the Metropolitan Line's City terminus [3].
