The provided wikitext does not contain information about a castle named "Mjøskastellet." Instead, the content exclusively describes Mjøsa, which is the largest lake in Norway and the fourth deepest in Europe. Located in the southern part of the country within the Innlandet and Akershus counties, this glacial fjord lake sits approximately 100 kilometers north of Oslo. The text details its vast physical characteristics, including a length of 117 kilometers, a maximum depth of 453 meters, and a surface area of nearly 369 square kilometers. Major cities situated along its shores include Hamar, Gjøvik, and Lillehammer, with the island of Helgøya located within its waters.

Because the source material focuses entirely on hydrography and geography rather than architecture or military history, no details regarding a construction year, architectural style, or specific historical significance of a castle can be extracted. The text highlights the lake's immense volume, noting it holds significantly more water than Norway's second-largest lake by volume, Røssvatnet. It also explains that the lake's deepest basin lies roughly 332 meters below sea level, making it deeper than many coastal sea inlets. The primary water inflow comes from the Gudbrandsdalslågen river, while the Vorma river serves as its sole outflow.

Consequently, there is no information available in the provided text about the current use, condition, or interesting history of a structure called Mjøskastellet. The document serves as a geographical profile of the body of water itself, detailing its tributaries, catchment area, and elevation. Any description of a castle by this name would require sources outside of the provided wikitext, as the current content is limited strictly to the natural features and statistical data of Lake Mjøsa.
