Calle de Oltra
The street bears the surname Oltra, common in Valencia and Alicante, whose exact holder cannot be documented. It does not appear in the 1888 street guide of the Guindalera neighbourhood, which places its opening or naming in the first decades of the twentieth century.
This residential street belongs to the Guindalera neighbourhood. Its history begins with the Castro Plan of 1860, when the land was opened to development. Between 1860 and 1864, the owners of those fields joined forces to parcel the ground and sell holdings. The first houses appeared in 1874, and by 1888 the neighbourhood already had 762 inhabitants and a handful of named streets. Calle de Oltra does not appear on that list, a sign it opened later.
The surname Oltra offers two possible roots: one points to Oltà, a hamlet of Benissa in the Marina Alta of Alicante; the other to the Romance word oltra, from the Latin ultra, ‘beyond’.
And here comes the intriguing part: no one knows whom the street honours. Neither Répide nor the classic guides identify the holder. The most reasonable explanation points to a plot owner or developer, though no document backs it. It should not be confused with Calle del Padre Oltra, in Carabanchel.
