The principal towns are Bikanir, the capital, Churu, Rajgarh, Ratangarh and Reni.
The picture gallery is equally important in its way, affording a survey both of the earlier Bolognese paintings and of the works of the Bolognese eclectics of the 16th and 17th centuries, the Caracci, Guido Reni, Domenichino, Guercino, &c. The primitive masters are not of great excellence, but the works of the masters of the 15th century, especially those of Francesco Francia (1450-1517) and Lorenzo Costa of Ferrara (1460-1535), are of considerable merit.
The cathedral is adorned with many valuable objects of art, paintings and sculptures, by such artists as Veit Stoss, Guido Reni, Peter Vischer, Thorwaldsen, &c. Part of the ancient Polish regalia is also kept here.
In the palace chapel are pictures by Rembrandt, Nicolas Poussin, Guido Reni and Annibale Caracci.
Kagul, on the Pruth, and Reni on the Danube (the place to which Alexander of Bulgaria was carried when kidnapped by the Russians in 1886), are small, but lively, river-ports.
