Correccions

Hello everyone, I'm a student from Perú and I have a task from the university, I have to write about one of the most important museum in my city (the Real Felipe Fortress), but everything should be in english.

I've been write it but I'm a begineer so, Could you help me to correct this first part,please?: The Real Felipe fortress was the most important fortress in America.

It was built from Spain, in 1747 the viceroy "José antonio Manso de Velasco" (that's the viceroy's name) started the construction and the Viceroy "Manuel de Amat y Juniet" finished it in 1774; the area is 70000 square meters, the perimeter is 1580 meters and the form of the fortress is a pentagon each corner is call "bastion", the walls was made with rocks from San Lorenzo island and the material to blinded the rocks is "CALICANTO" and that is a mixture of water, sand, cal.

the first bastion is the artillery park,in there you can see 3 models of cannons: Swedish, French and Japanise.

And thoose models of canos were used by Perú in 1941in the war with Ecuador.

That is the first par , as soon as posibleI I'll writing the others parts.

Thank you for yout help.
