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.

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).

Even objects which are a functional requirement, can be designed in an attractive way. In the Saxon town of Schkeuditz, in Germany, a plain support for a slope has been built as a gigantic sofa made of granite, which invites one to sit down, linger and enjoy.

The obelisk of Hatshepsut, built in the year 1457 BC, during the XVIII dynasty, is the second biggest of all the ancient Egyptian obelisks. Made of one single piece of pink granite, it has a height of 28.58 metres and its weight is 343 tons. It is located in the Big Temple of Amon, in Karnak.
