1057-Flat Arch – Old Town, Panama

Originally constructed in the 17th century, the church and convent of Santo Domingo were never rebuilt after a fire that destroyed them in 1756. The only thing that did survive – for centuries – was the Flat Arch (Arco Chato) sitting at the entrance. The Arch stood as a testament to the fact that Panama was spared from major seismic activity and contributed to the case to build a major canal in the area. (stolen from the web)
