The Castle is as the name suggests immediately adjacent to the grade 1 ruins of Halton Castle. The pub itself is the 18th century grade 2* listed courthouse. There are magnificent views towards both Liverpool and Cheshire.

There are two rooms downstairs, each with an open fire hearth. Upstairs there is a function room with a small bar (no real ale).

Two cask beers kept on tap. The Spitting Feathers Best is badged as Castle Bitter.

Nearby is the Cheshire Library, one of the earliest free library's in England.
