Just over the town of Ivana, stands the oldest stone house in Batanes known as the House of Dakay. Built in lime and stone in 1887, it is the only 5 structures that survived the frightful earthquake in September 13, 1918 which literally leveled the the whole town of Ivana to the ground. Most of the structures like the shutters and floors still retains the original materials. Only the thatched cogon roof has been changed every thirty years since 1917. It is a small impressive structure which earned a UNESCO heritage building title.
