The Spanish pattern of economic growth during the last two centuries is quite unique. In the nineteenth century the country remained outside the process of industrialization, but during the twentieth century he has joined the small group of developed economies. This article tests the existence of discontinuities between 1850–1936 in the series of PNB, industrial production and private and public investment by utilizing recent developments in the econometric analysis associated with the work of Perron and Zivot and Andrews. The results confirm the continuity of the Spanish growth during the decades considered. However, they also show two breakpoint years: 1870 in the serie of industrial production and 1919 in the data of public investment.
