Source-derived summary

Avinguda Diagonal (Catalan: [əβiŋˈɡuðə ði.əɣuˈnal]; Spanish: Avenida Diagonal; transl. 'Diagonal Avenue') is the name of one of Barcelona's broadest and most important avenues. It cuts the city in two, diagonally with respect to the grid pattern of the surrounding streets, hence the name.

It was originally projected by engineer and urban planner Ildefons Cerdà as one of the city's wide avenues, which along with Avinguda Meridiana would cut the rationalist grid he designed for Eixample (Catalan for 'Expansion'). Both would meet at Plaça de les Glòries Catalanes, which Cerdà envisioned as the new city centre. However, Plaça Catalunya, equally a new addition to the city of Barcelona, and connecting Ciutat Vella and Eixample, and therefore occupying a more privileged position in the urban area, would finally become the centre. Avinguda Diagonal remains to this day a much-transited avenue and many companies and hotels use it as a privileged location, as can be seen in its architecture.

The avenue starts in the Les Corts district on the western edge of the city and runs to the Sant Martí district on the eastern edge. To its west, it connects with the Lleida-Madrid highway and Ronda de Dalt in the neighbouring municipality of Esplugues de Llobregat. To its east, it meets the Ronda del Litoral on the border with the municipality of Sant Adrià de Besòs. It is consistently 50 metres (160 ft) wide and about 11 kilometres (6.8 mi) long.

Editorial summary

Begin with the source’s own compact description: “Avinguda Diagonal” is thoroughfare in Barcelona, Spain. The dossier treats that line as a proposition to test through Avinguda, Diagonal and thoroughfare, not as a finished interpretation.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 238-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 1860. For this dossier, Avinguda, Diagonal and thoroughfare is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “thoroughfare in Barcelona, Spain” 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.

Evidence profile

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
