Rochester castle

Rochester castle (Kent) stands above the river Medway whose crossing it controlled. The first castle on the site was an enclosure within the Roman city walls. The present castle, also originally a ‘ringwork’, was begun by Gundulf, bishop of Rochester, for William Rufus 1087–9. The castle was transformed by the addition of a tower keep built 1127–40, after Henry I had granted the castle to the archbishop of Canterbury and his successors. The keep, which is 70 feet square and rises to the height of 113 feet to the parapet, was designed to be the defensive heart of the castle and also to contain the best residential accommodation, which is arranged on three floors above a basement. The grandest suite, presumably intended for the archbishop himself, is on the second floor and has its own chapel. The defensive strength of the castle was demonstrated in 1215 when rebel barons held it against King John. The royal forces took the castle only after they managed to dig a mine under the south-east angle tower, which caused the tower to collapse.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
