I need help for a spanish project

I was assigned a project for my Spanish class to get information on Santo Domingo. And I can't seem to find a thing on what I need. If anyone can help me I would really appreciate it. I need Santo Domingos population,size of the city,and an historical Monument. If anyones knows something on it, please write back. Thanks

Santo Domingo's population is about 2.5 million, 250 square kilometers. Historical monuments: Columbus Lighthouse, Cathedral of Santo Domingo (first in the New World), or Columbus Palace (Alcazar). See Santo Domingo in the travel section.
