This river flows straight through London and is seen in two installments of the Professor Layton series.
Professor Layton and the Eternal Diva
In the Eternal Diva, the River Thames appears as a cameo. During the Cold Open of the film, the River Thames lies under the Tower Bridge, where Professor Layton goes to solve the case as to what exactly has happened to the silenced bell of Big Ben. Here, Layton reveals that the kind old lady near-by is none other than the sinister Don Paolo. With his disguise blown, Paolo retreats using a propeller hidden within his umbrella, flying over the river. Hastily, Inspector Chelmey, Barton, Luke and Layton chase down Don.
Professor Layton and the Unwound Future
In the Unwound Future, the River Thames makes its first real appearance. The river appears in both London and Future London. In Future London, Layton travels over the river in order to get to Chinatown. The river separates Future London in between the core parts of the city and Chinatown. Across the river, on the north side, is Dimitri's Research Facility and an odd lighthouse. Along the River Thames is also a location known as the Thames Arms. The Thames Arms is a riverside restaurant on the western side of the River Thames.
- The River Thames is named after the stories of Old Father Thames.
