The Pavillion Nº 1
Contructed in 1878. Inside there were 12 oak vats for storing wine and also the old harvesting machinery. The building was reworked in 1904 to allow an increase in the ceiling height.
These wood vats called "Tinas" were replaced in 1899 by 5 of a larger size ordered by Don Rafael López de Heredia Landeta from the vat maker, Monreal in Zaragoza. They were outdoor for many years covered with plaster to protect them against the elements. In 1907 a carpenter from Haro: Juan Sagredo, finished the roof of the whole building following the project of the architect Julio Martínez Zapata.

When the fotographer Manuel Torcida Torre came to the winery in April 1910 this building had no floor. The floor was made in 1913 by a Company from Bilbao called "Gamboa y Domingo". Near a column within building there is a time capsule buried at the original time the building was being made in 1906.
From 1914, it had, already, a floor but it was still open to the rail station. This wall was closed in 1960.
