After almost 2 years of rehabilitation work, the Medieval Market of Unicastillo, Zaragoza, was inaugurated last 29 July as the headquarters of the UNCASTILLO Foundation. From here the Foundation will develop all its cultural program and patrimony management. " In the rehabilitation of this building, as far as possible, the original structure has been maintained. The reconstruction realized has been done only when the conserved remains have provided sufficient data about the original form.

It is the third biggest mosque in the world, with the capacity for 30000 people. Its is named after the founder and President of the United Arab Emirates, who is buried here. About 220.000 square metres of stone was used in the whole project.

One distinguishing quality about Central Europe that never fails to impress foreigners is the traditional emphasis on technical training. One reason the world is so enthusiastic about the economic possibilities of the countries that have entered the European Union only two years ago, is not just the lower labour costs, but the generally very high quality of manpower. This technical training is not something that was imparted to the population in the last few decades, there is a long tradition of it.

In the Romanesque period the construction of churches used to be the responsibility of what was known as Magister Muri. He was represented with a Virga (baton in hand).

The biggest application of granite in most countries tends to be either in the construction industry or kitchen tops. Rare is the country where the biggest use of granite, measured in cubic metres or even value, is the tombstone industry. Poland is one such country.
