Holborn Viaduct is a bridge over the old Fleet River, included in Syndicate's database. Its database entry, written by Shaun, covers Queen Victoria unveiling it in November 1869.
The viaduct was meant to be both a road and a showpiece, spanning the length of the Fleet River valley.
Shaun Hastings writes the entry in his usual dry style, admitting at one point that he added a colourful detail only because he suspected the reader's attention was drifting during a piece about a viaduct. It is a good example of the commentary the Helix database adds to otherwise plain landmark records.
10 Downing Street

The Adelphi Theatre is a London playhouse in the Jack the Ripper expansion. It ties into the Woody Shinnings bounty, where Inspector Abberline asks Evie to bring in the understudy who murdered the actor Richard Altman.
Admiralty
The Admiralty is a government office on Whitehall in Westminster, one of the period buildings you can climb and read about in the in-game database. No memory centres on it.
