I'm not sure what you mean by holy, but the Buddha is revered, or greatly respected for the realizations he had about the human condition and the teachings he offered to quell suffering as a result of those realizations.
A holy figure is one related to a deity. Buddhism has no holy figures as it has no deity. The figure of Buddha is often represented in Buddhist temples and shrines. This does not make it a holy figure, rather it is a revered figure. It honours the man who determined the way by which each of us may find our way out of the cycle of death and rebirth and to enlightenment.
Buddha did not want to become "Holy" he wanted to become enlightened
The Buddhist figure is the God of the Buddha religion. His name is Gautama Buddha, who was a spiritual figure who's teachings founded Buddhism, so the Buddha figure is Gautama the original Buddhist
Buddha wrote no books holy or otherwise. Buddhism rejects the concept of "holy" as it implies reliance on a deity. The records of Buddha's discussions and the analysis of his philosophies was done by others.
The Buddhist holy place is called Here. Lumbini where Buddha was born, Bodh Gaya where Buddha became enlightened, Sarnath where Buddha gave his first sermon, and Kushinagar where Buddha died are the most important holy places for buddhists.

There is no Holy City. I would say that there are four holy sites, which are: 1) Lumbini, Nepal - The Birthplace of Buddha 2) Bodhgaya, India - The place at which Buddha became enlightened. 3) Sarnath, India _ the place where Buddha gave his first sermon; and 4) Kushinagar, India- The place where Buddha left this world.
A Buddha figure symbolizes someone who is awake. In other words, a Buddha is someone who is enlightened, who is no longer deluded by dualistic concepts.
I know of no saint who predicted Buddha's birth, but the hermit and holy man Asita predicted to Buddha father, King Suddhodana, that his son would be either a great ruler of men or a great holy man.
