The monoliths in St. Petersburg are so exceptional in number and often so gigantic in dimension as to call for special mention. The monolith obelisks of ancient Egypt are scarcely more remarkable. In addition to the magnificent columns, each sixty feet high, which sustain the four porticos of the Cathedral of St. Isaac, are fifty-six monoliths, also of granite from Finland, thirty-five feet high in the Kazan Cathedral; likewise the noble entrance-hall of the Hermitage is sustained by sixteen monoliths, and the magnificent room which receives the treasures from the Cimmerian Bosphorus has the support of twenty monoliths. But the greatest single block of modern times stands in front of the Winter Palace, as a monument to Alexander I. The height is eighty-four feet, and the weight nearly four hundred tons. The story goes that the contractor in Finland, finding that he had exceeded the required length, actually cut off ten or fifteen feet. The vast granite quarries of Finland supply the Tsars with these stupendous columns, just as the granite quarries of Syene on the Nile furnished the Pharaohs with obelisks. These enormous masses are too heavy to be conveyed on wheels, the only practicable mode of transit is on rollers. In this way each of the sixty-feet columns for St. Isaac's was transported across country all the way from Finland. Each column represents so incredible an amount of labour as to make it evident that monoliths are luxuries in which only emperors can indulge. And even when these heavy weights have reached their destination the difficulty next occurs how to secure a solid foundation. St. Petersburg was once a swamp, and so rotten is the ground that it would be quite possible for a monolith to sink out of sight and never more be heard of. To provide against such contingencies a forest of piles was driven into the earth at the cost of L200,000 as the foundation of St. Isaac, and yet the cathedral sinks. Like causes render the roads of St. Petersburg the worst in Europe; winter frosts, which penetrate several feet below the surface, seize on the imprisoned waters and tear up the streets. The surface thus broken is so destructive to wheels that I have known an Englishman, who, though he kept four carriages, had not one in a condition to use. The jolting on the roads is so great as to make it wise for a traveller to hold on fast, and when a lady and gentleman ride side by side, it is usual for the gentleman to protect the lady by throwing his arm round his companion's waist. This delicate attention is so much of a utilitarian necessity as in no way to imply further obligations.
