Vigan is the capital of the Philippine province of Ilocos Sur and a World Heritage site.  Most of the city is well preserved as one of the last Hispanic cities in the Philippines.  Much of the city, of course, has been modernized but its colonial heritage is largely preserved.   You can choose to take the plane but for the best Vigan experience you should go there by bus.

The Vigan Cathedral is the main church of the city

 The Museo di San Pablo is the national museum

of Vigan and houses a collection of mementos of early

Philippine life

 Baluarte is Gov. Chavit Singson's Xanadu.  It is a mini-zoo

that houses such animals as ostriches, camels, peacocks and alpacas

to name a few

Bantay Church and Belfry is another of the many 

churches in Vigan and from the tower you could see the city

at large

 Don't let the unimposing picture fool you.  Syquia Mansion

is one of the must-see places in Vigan; it preserves the

Chinese-Spanish aristocratic way of life apart from also

being the residence of President Elpidio Quirino

Finally, the must-see site (and the closest) site is the

Calle Crisologo, a preserved Hispanic cobbled street wonder

amidst modernized streets in Vigan.
