After that, visitors entered the city by passing over the moat on a drawbridge, through the outer gatehouse, over a second bridge and through the inner gate.

The tower was demolished in 1748 by mayor Christian Ulrich Grupen  [de] to make way for New Aegidien Town.

[de ] As a result of the conversion of Hanover's main roads into the Cityring in the 1950s, the square was made significantly more spacious.

[2] The Aegi Overpass often had to be closed in winter due to ice build up, was only authorised for cars weighing less than 3.5 tonnes (7,700 lb), and was limited to a top speed of 30 kilometres per hour (19 mph).

The Stadtbahn received a raised rail platform designed by the architectural firm Wiege and ran from Thielenplatz to the entrance of Aegidien Gate Square.

In 2003 planning began for further renovations, which would begin in November 2004, after the waiting period for the previous project imposed by the Municipal Transport Financing Act had expired.

The bus lane created in the previous project would be abandoned as far as the intersection with Hildesheimer Straße to permit an easier route for the buses.

The remaining space was converted into the so-called Aegidien Forest (Aegidienwald), designed by Dominik Geilker and Stefanie Schmoll, landscape architecture students at the Leibniz University Hannover, who were supervised by Professor Udo Weilacher and civil engineer Thomas Göbel-Groß.

[5] The Hanover savings bank, Sparkasse Hannover, established its headquarters here in 1922 and installed counters on the ground floor.

Of architectural interest is the so-called Gate House Hanover (Torhaus-Hannover) located between Marienstraße and Hildesheimer Straße.

[8] Initially, the Hanoverian architecture firm BKSP planned an office building with nine stories, later this was raised to ten.

On the connecting level (-1) of the station (exiting on to Hildesheimer Straße) a wall features a large reproduction of the Aegidien Gate as it appeared in 1620 according to Arnold Nöldeke's [de ] book Die Kunstdenkmale der Stadt Hannover.
