While town twinning has played a crucial role in reconciliation and reconstruction processes in Europe after World War II, urban historians have not yet paid sufficient attention to it. This special issue thus addresses this historiographical neglect through a set of case-studies that examine the role of twinned cities in post-war reconciliation and reconstruction between former enemy nations and across the ideological fault lines of the Cold War. The framework that underpins all contributions rests on the use of ‘twinned cities’ as an umbrella term to denote various forms of inter-municipal links and builds on similarly broad definitions of ‘reconciliation’ and ‘reconstruction’.

This article addresses the beginnings of the twinning relationship between Coventry and Kiel to introduce and exemplify the idea of ‘urban internationalism’ as a new lens onto urban histories of town twinning initiatives and a contribution to the historiography of British town twinning. Focusing on paradiplomatic initiatives by municipal officials, religious dignitaries and other citizens in Coventry and Kiel, the article examines the role that cities played in British–German reconstruction and reconciliation in the period from the end of World War II until the formation of the Federal Republic of Germany in 1949.

Formalized in the 1970s through the Middlesbrough–Oberhausen Town Twinning partnership (Partnerschaft Oberhausen–Middlesbrough), the connection between the two post-industrial towns dates back further to informal connections in the early 1950s and an age of reconciliation between the two nations. This article explores the origins, mechanisms, benefits and challenges of town twinning by drawing upon a rich body of empirical evidence from local authority records, press coverage, interviews and community reminiscence. The study provides the first academic analysis of the changes, challenges, continuities and continued relevance of town twinning in one of Britain’s leading pro-Brexit areas.

This article provides a fresh perspective on the history of East German town twinning in the early era of détente. While previous studies have analysed East German town twinning solely as an instrument of the Socialist Unity Party (Sozialistische Einheitspartei Deutschlands, SED) to establish paradiplomatic relations in Western Europe, I explore the dynamic inter-relation between global, national and local actors and the ambiguities of urban détente. I reveal the importance of the German Association of Towns and Municipalities (Deutsche Städte- und Gemeindetag, DStuG), the East German association of municipalities, which crucially shaped the East German concept of urban détente through practising trans-local exchange. The role played by the DStuG was backed by the United Towns Organization (UTO), a non-governmental organization founded in 1957 whose aim was to form a global network of cities beyond the East–West divide. In 1960, the DStuG joined the UTO as a member and consciously used its new position to expand its scope and improve its national status through actively working on the conceptualization of urban détente. However, the conflicts between the East German foreign ministry and the UTO grew bigger, resulting in the marginalization of the DStuG and town twinning in the SED’s concept of détente. These conflicts encouraged the UTO to redefine its global approach.

In 1959, East German Dresden and western Polish Wrocław were twinned to promote cross-border contact between political leaders, worker delegations and cultural groups. Officially formed to promote worker solidarity among friendly East Bloc regimes, in practice the inter-relationship exposed a troubling history that was just below the surface. In the recent aftermath of Nazi defeat, the German population of Breslau (over 600,000 people) had fled or been expelled from a city which had long been German. At the same time that Breslau became Polish Wrocław, a significant number of old Breslauers settled in the East German province of Saxony, especially Dresden. This article uses archival and published sources to show how, under the umbrella of worker exchanges, field trips and official amity, the sister-city programme unintentionally became a venue for German exiles from Breslau to encounter Wrocławian delegations in Dresden and to return ‘home’ to discover Wrocław’s post-war Polish reality.

The heritage of World War II left an indelible mark on the relations between Italy and Yugoslavia. During the détente period, however, these two countries were able to overcome many historical resentments and established a fruitful co-operation in Cold War Europe. This article questions the engagement on state, regional and municipal levels and analyses the role of twin cities in this multilayered process. With the help of primary sources, we learn how the heritage of World War II played an important role in building new forms of post-war co-operation. In fact, post-war twinning is often the result of shared anti-fascist activities from the war years. However, this is not confined to communist municipalities or ‘red’ regions in Italy on one side, and socialist Yugoslavia on the other, but is a more fluid and flexible practice which involves historical ties, geographical positions, personal capacities and economic needs.

Town twinning is often seen as a linear driving force of European integration. This article argues that town twinning’s historicity is more complex. The initial post-war period, according to today’s practitioners’ accounts, was characterized by a high degree of personal involvement which transformed into an exposure to relationship uncertainty. By way of contrast, twinning practices since the 1990s are reported as being driven by a more managerial logic. The shift from the imaginary of ‘reconciliation’ to that of ‘integration’ comes along with a change in twinning practices, the distribution of responsibilities and the share of personal involvement and exposure.

This article builds on recent works which challenge the dichotomy between religion and modern urban planning. The article focuses on a case-study in the Alsatian city of Mulhouse during the nineteenth century. Over a period of 30 years, Catholic parishioners and clergy repeatedly petitioned the town’s Calvinist industrial and municipal elite for a church to be built in the paternalist cités ouvrières housing district, culminating in the eventual construction of the church of Saint-Joseph by 1883. Through a close analysis of the archival records of these petitions, the discussions they sparked and the shifting local and national political dynamics of the city, this article argues that religious groups used myriad tactics to engage in modern planning and that municipal authorities were won over by these tactics if they were politically expedient.

The late nineteenth-century harbour districts, or so-called ‘sailortowns’, are generally depicted as deterritorialized ‘enclaves’ of heightened globalized transience. However, these neighbourhoods were just as much shaped by semi-durable local labouring communities. This article studies lodging houses as facilitators of global and local entanglements in harbour districts from a socio-cultural perspective, with Antwerp in the late nineteenth century as a case-study. Analysing the spatiality, materiality, sociability and people of the lodging phenomenon, it reveals that next to the highly transient seafarers, sailortown accommodated a diverse yet largely local population of small entrepreneurs and their families right between transience and permanence.

This article discusses houses on the periphery of Barcelona and in particular in the El Carmel neighbourhood, which were built by poor country-to-city migrants from southern Spain in the post-World War II period. They were constructed following two typologies: barracas (sheds), one-storey huts on an irregular street plan, and coreas (‘Korea houses’), more formally looking one- to three-storey structures lined up on orderly laid-out streets. Based on archival documents, contemporaneous publications and interviews with former autoconstructores (self-builders), the article analyses both social conditions and physical structures. While these buildings were often unauthorized and constructed by informal means, they were just as often built with the landowner’s consent, involving architects and building professionals, and retroactively legalized. The article concludes that in this respect Barcelona’s ‘informal neighbourhoods’ in fact straddled the realms of the formal and the informal, to the extent that the habitual distinction between formal and informal architecture has to be considered inadequate.

This article delves into the post-war urban planning of Racibórz (Ger. Ratibor), a mid-size city in Poland, shedding light on the socialist city’s historical roots and its adherence to socialist urbanism models. Using planning maps and other archival documents, it examines the reconstruction process that aimed at creating green spaces and quality housing, while at the same time revealing its medieval past. The article also investigates the city’s deviation from known recovery patterns and highlights a lesser known approach to creating a city with a national form and socialist content. Overall, this research offers a comprehensive exploration of a reconstruction process in a mid-size city, enriching the understanding of European post-war urban history.

Between 1964 and 1969, the Ford Foundation developed the Community Facilities Program in Chile, which articulated technical and financial assistance in the field of architecture and the training of local experts, in addition to its action in the renovation of state structures related to housing and urban planning. In this context, the design strategy introduced innovations based on architectural research that were a pedagogical novelty, which contributed to the discussion on the role of technical assistance in the Southern Cone, redefining the relationship between philanthropy, state and University.
