Tambroso
mountain in Portugal
Tambroso is a mountain peak on the Azorian island of Faial. It is located in the civil parish of Ribeirinha, in the municipality of Horta. The mountain, as well as its surrounding land-forms, is geographically close to the volcanic caldera at the center of Faial. The eruptive igneous rocks produced by this caldera forms the base of Tambroso, as well as many other peaks on Faial Island. The whole series of peaks has a maximum elevation at Cabeço Gordo, which is 1,043 metres (3,422 ft) above sea level.
Geography and geology
The elevation of Tambroso itself reaches to 506 metres (1,660 ft) above sea-level. It is situated near another local peak, Alto da Pedreira, and the town of Ribeirinha. Climatically, the mountain is situated in a temperate ocean climate, as is the rest of Faial Island.
The rocks that make up much of the Azores are generally related to a triple junction which produces Neogene-aged, intrusive and extrusive/ eruptive, mafic igneous rocks, and sedimentary formations derived from them. The rocks that form Tamborso are mapped as part of the Cedros volcanic complex.
This brief starts where responsible research should: with the source description of “Tambroso” as mountain in Portugal. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as mountain in Portugal. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 16, 2026. The linked authority identifier is Q10378023. Authority coordinates are 38.600, -28.650. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
