Casa Padellàs (Barcelona History Museum MUHBA)

This guide to Casa Padellas, home of Barcelona's history museum MUHBA, follows a Gothic palace that stood in the path of a new modern avenue in 1931 and was cut apart stone by stone and rebuilt in Placa del Rei rather than demolished. It traces what workers hit when they dug the new foundations for the transplanted palace: buried streets and workshops of Roman Barcino, two thousand years older than the city above it. You'll hear how far archaeologists kept digging outward from that single foundation pit once the excavation began. The tunnels now run beneath the square itself, so plan to see both the house above and what lies under it.
