The Philippines is a predominantly Catholic nation and no country in ASEAN can rival its centuries-old churches, with their antique religious objects. Fascinating churches, to be found around Metro Manila are: the Malate Church with its images of Our Lady of Remedies; the Las Pinas Church, with its 165-year-old organ made entirely of bamboo; and San Sebastian Church built in 1981, the only Gothic steel church in the country.
What kind of church is San Sebastian Church?
1.San Sebastian Church is a Gothic steel church.
2.San Sebastian Church is the only Gothic steel church in the country.
I can't decide which answer is suitable for the question "What kind of--". I like both as they can describe the types of Church.
