Fictional Cities

There are two kinds of fictional cities.

Entirely Invented

Poul and Karen Anderson created Ys ex nihilo. The name is legendary but the Anderson's created:

Taranis Way

Lir Way

Elven Gardens

Star House

Dragon House

Goose Fair

the Fishtail slum

the Sacred Wood

"the hundred towers" (less than 100)

the sea wall and gate

Scot's Landing

- which we know as if we had been there.

Susan Howatch created Starbridge with its Eternity Street although this city is based on Salisbury.

Real But With Additions

In Poul Anderson's Time Patrol series, New York is as we know it but there are additions like Manse Everard's apartment and a Patrol warehouse.

Susan Howatch's London has St Paul's, the Abbey and (fictional) St. Benet's and the clergy refer to a large southern diocese (Starbridge) without naming it.

Stieg Larsson's Stockholm includes Kvarnen (real), Samir's Cauldron (fictional but based on a real place) and we are told the real addresses of fictional people and organizations. Larsson's characters travel through real places to the fictional Hedestad on the Norrland coast.
