The 18 km (11 mi) of its coasts are mostly rocky; the western and northern part includes some natural grottoes, unprotected landings, with a few small beaches, in general here the coast is usually very steep, rocky. The eastern coast, on which the port of Carloforte lies, is more protected low and sandy.

Why this record matters
“San Pietro Island” is worth following because a concise public description often conceals a longer documentary argument. Here, Pietro, Island and island provides the most credible route into that argument.
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 Apr 22, 2025. The linked authority identifier is Q912934. VIAF identifies the subject as 315126757. Authority coordinates are 39.146, 8.273. 2 of 2 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 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.
