Render rich text in MVC View?

I am creating an asp.net MVC application, and I am using rich text in order to store rich text inside my database.

While fetching the rich text from the database and displaying it on the Details page, I no longer see the formatted data. Rather I see the the plain html (for example < p>< b>< strong>rich text sample< /strong>< /b>< /p>).
How can I display rich text as it is formatted and not as plain html using an Html text helper like Html.TextArea?

[AllowHtml]
public string Description { get; set; }

I have tried setting my View for the Description like this instead of DisplayFor, but it still doesn't work:

<dd>
    @Model.Description
    @*@Html.DisplayFor(model => model.Description)*@
</dd>
