The Torre del Palau in Manacor is the only fragment remaining of a royal palace dating back to the late 13th/early 14th century. The palau compound was built under the orders of King Jaume II as a temporary palace for the Reis de Mallorca. Quite why Manacor was chosen for the location of this palacio away from the capital, Ciutat de Mallorca, I am afraid I cannot tell you. Perhaps someone out there will be able to enlighten us on this.
When I went there the other day, scaffolding was obstructing the views of the tower (see photo below). But I could hear workmen busy doing the place up and, with a bit of luck, one may be able to visit the interior of the tower once building work has finished. I have never been inside; the torre has always been closed whenever I attempted a visit. Next time lucky, perhaps.
