A station named Aldgate East opened nearby eight years later[8] and is served today by the District and Hammersmith & City lines.

[9] However, this change also forced an awkward doubling-back at Aldgate, reducing the desirability of the line for local traffic and greatly increasing the cost of construction due to high prices in the City of London.

[n 1] The station building has a six-bay façade clad in white faïence with original features including 1920s shopfronts with green marble and pink granite stallrisers, a half-hexagonal canopy of glass and metal suspended by elegant metal ties, leaded light first floor windows, dentil cornice, two ornamental lamp brackets and a frieze bearing moulded lettering and the Metropolitan Railway monogram.

In 2005, one of four suicide bombers involved in the 7 July terrorist attacks detonated a device on a C-stock Circle line train from Liverpool Street as it was approaching Aldgate.

[13] Of the stations affected by the bombings, Aldgate was the first to be reopened, once police had handed back control of the site to London Underground following an extensive search for evidence.

In the story, the body of a junior clerk named Cadogan West is found on the tracks outside Aldgate, with a number of stolen plans for the Bruce-Partington submarine in his pocket.
