Question: In Rome, Nero and his architects used mosaics to cover some surfaces of walls and ceilings in the Domus Aurea, built 64 AD, and wall mosaics are also found at Pompeii and neighbouring sites. However it seems that it was not until the Christian era that figural wall mosaics became a major form of artistic expression. The Roman church of Santa Costanza, which served as a mausoleum for one or more of the Imperial family, has both religious mosaic and decorative secular ceiling mosaics on a round vault, which probably represent the style of contemporary palace decoration.
Is there an answer to this question: The church of Santa Costanza is in what country?

Answer: Rome

Question: In 1845, Ireland was hit by a potato blight. In the next four years over a million Irish people died and another million emigrated in what became known as the Great Famine. In Ireland, Victoria was labelled "The Famine Queen". She personally donated 2,000 to famine relief, more than any other individual donor, and also supported the Maynooth Grant to a Roman Catholic seminary in Ireland, despite Protestant opposition.
