In 1901, the board of directors of Portuguese State Railways ordered a study to be carried out on the road connections to its stations and halts on the Douro Line.

After a proposal by the then president of the Pinhão Parish Council, António Manuel Saraiva, to decorate the station with azulejo tiles, which had been turned down by the railway company, in 1935, the Instituto dos Vinhos do Douro e Porto (Port Wine Institute) donated tiles to cover the station, both at the front and along the platform.

Created in 1933, the institute's objectives were to promote and defend the Port wine brand nationally and internationally and to advertise the sector.

The station is now completely decorated by the tiles, which depict landscapes and traditional activities of the region, especially the cultivation of vines, the treading of the grapes, and the transport of the wine in rabelo boats down the river to the cellars in Vila Nova de Gaia.

[4] Pinhão station won the SOS Azulejo Conservation and Restoration Intervention Award in 2013 for its contribution to the enhancement of Portuguese heritage through the rehabilitation of the tile panels.
