Errekalde palace, where Laboratorium museum is located.

Errekalde Palace is a 19th-century building. It started out as an old medieval tower which was remodelled in the 16th century to give it a more palatial aspect. However, during the social unrest of 1718 the house went up in flames and was very seriously damaged. New improvement works were carried out throughout the second half of the 18th century, but it wasn't until the 19th century when large-scale works took place within the Errekalde building: there was a desire to bring a military and medieval feel with certain structural details and adornments, but what was actually created was a romantic 19th-century house.

To appreciate this one has simply to study the size of the palace, its large and numerous alcoves and windows, the entrance stairway and main door, the inner staircase and French windows, the height of the interior spaces and their layout and decoration, or the carpentry of the doors and windows.

Errekalde Palace was the residence of the Count of Peñaflorida, Director of the Royal Seminary of Bergara, during part of the 18th century.
