Book excerpt: This book uses the concept of "arrival spaces" to examine the relationship between migration processes, social infrastructures, and the transformation of urban spaces in Europe since the mid-19th century. Case studies cover cities from London to Palermo and from Antwerp to St. Petersburg, including both metropolises and small towns. The chapters examine the emergence of settlement patterns, the functioning of arrival infrastructures, and the public representations of neighborhoods which have been shaped by internal or international migrations. By understanding these neighborhoods as spaces of arrival and as infrastructural hubs, this volume offers a new perspective on the profound impact of migration on European cities in modern and contemporary history. This volume makes a valuable contribution to both migration research and urban history and will be of interest to researchers and students studying the relationship between cities and migration in Europe’s past and present.
