**The Salt Lake City Library**  The Salt Lake City Library building was opened in 2003 in the state of Utah in the United States, and was designed by architect Moshe Safdie. In this text, we go to expose an aspect very important in the architecture; the circulation, that can be horizontal or vertical, depending to the needs and uses of the space.

Moshe Safdie

First let's go to talk about the horizontal circulation, defined for the square Library, a free space, made with limestone from Israel, which counts with the adequate size for all kind of people, stores, as well as the studios of the radio station. Also this square counts with a very good circulation plan that integrated the city with the square using beautiful paths with oblique approach, that give more dynamic to the place, keeping the calm and given a breath to the people who wants escape of the city rhythm, so, to definite and separate those stages the architect created an odd but modern and beautiful wall that covers part of the square, allowing see the outside across them.



Now, following with the outside style, we found the same material, the limestone, for the first floor of the library, and for don't break the outside with the inside was used concrete and glass for the five floors of the structure to use the nature light too, and in the roof a garden, open to the public, offering a 360°of view of the Salt Lake Valley.

So, for enjoy all the library was necessary create a vertical circulation plan that permit the access to all kind of people, and how this is a public building is almost obligatory the existence of a ramp, because allow the pass of the people with special conditions too.Well, other element of the vertical circulation is the stair and the three crystal elevators, those permits ascend to the gallery, to the auditorium, to the multi-area or to the roof-top green.

In conclusion, "Salt Like Library" is a huge structure where function an amazing public resource for the community of the state of Utah in the United States, offering an open access to the information and knowledge, and allowing that increase the quality of life, with more public and open spaces for all the people, mixing the community needs, the basic concepts of the architecture and the ecological methods.
