Castle of Lanhoso
building in Póvoa de Lanhoso, Braga District, Portugal

The Castle of Lanhoso (Portuguese: Castelo de Lanhoso) is a medieval castle located in civil parish of Póvoa de Lanhoso (Nossa Senhora do Amparo), municipality of Póvoa de Lanhoso, Portuguese district of Braga of Portugal.
History
The site on top of the mount had been occupied since the Chalcolithic period.
Between the 10th and 11th century, the castle existed as a series of walls and corners.
It was between 1071 and 1091 that Bishop D. Pedro, whose episcopate lasted between 1070 and 1091, supported the reconstruction of the castle's ashlar walls, over the pre-Romanic fortress, that originally defended the episcopal seat of Braga. An epigraphic plate in ashlar was located on the site, that reads: PETRIS AEPISCOPUS.
In 1121, D. Teresa of León sought refuge in the rebuilt castle, to which she was besieged by forces loyal to her half-sister D. Urraca, Queen of León. Urraca took Theresa captive. However, an intervention by Bishop Gelmires forced the two to an agreement, the Treaty of Lanhoso, that preserved the land holdings of both sides. Then, in 1128, she was imprisoned in the same castle, under the orders of her son, D. Afonso Henriques, after the Battle of São Mamede.
By the end of the 12th century or beginning of the 13th century, there was a Romanesque change in the construction of the keep tower, when the fortress was the centre of the region.
The castle was the site of a crime of passion, when the alcalde, D. Rui Gonçalves Pereira, the great-great-grandfather of D. Nuno Álvares Pereira, discovered the infidelity of his wife while away.

Why this record matters
The phrase “building in Póvoa de Lanhoso, Braga District, Portugal” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q5049786. Authority coordinates are 41.587, -8.281. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1071, 1091, 1070 and 1121.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
