The present building block has at least one load bearing surface, the load bearing surface of the block having mating interlocking portions comprising cores and protruding interlocks receivable in the cores. The blocks are configured so that each end of a block comprises a half interlock and adjacent ends of a pair of blocks in a course together define an interlock portion that interlocks with a mating full interlock portion carried by a block in an adjacent course of blocks. The basic building block has ends that are oblique such that rows having a preset radius can be formed or such that a linear row can be formed by placing one block front-to-back and an adjacent building block back-to-front. Disclosed are angle blocks with and without splitter wedges, stretcher blocks with and without splitter wedges, blocks for forming corners and posts, cap blocks, and blocks for capping posts.

What is claimed is: 1. A set of building blocks useful in forming at least a portion of a wall having two or more courses, each block comprising: first and second opposed faces; first and second opposed ends extending from the first face to the second face; first and second substantially flat and opposing load bearing surfaces extending, parallel to one another, from the first end to the second end and from the first face to the second face; a pair of end core portion, one formed in the first end and the other in the second end, the end core portions extending between the first substantially flat load bearing surface and the second substantially flat load bearing surface; a half interlock protruding from the first substantially flat load bearing surface at the first end of the block, the half interlock forming at least a portion of a periphery of one of the end core portions; and at least one core portion extending into the block from the first substantially flat load bearing surface, each of the at least one core portion being spaced apart from the half interlock and including a first opening approximately flush with the first load bearing surface and without an interlock, and a second opening approximately flush with the second load bearing surface and without an interlock; wherein, when the first ends of two of the blocks are positioned adjacent one another, in a first course of the two or more courses, the half interlock of each forms an interlock portion for mating within one of the at least one core portion of a third of the blocks, but not fitting within the end core portions of half interlocks, the one of the at least core portion of the third of the blocks being positioned in a second course of the two or more courses with the second substantially flat load beating surface thereof facing the first substantially flat load bearing surface of each of the two blocks; and when the core portion of the third of the blocks mates with the interlock portion, the second substantially flat load bearing surface of the third block comes into direct contact with the first substantially flat load bearing surfaces of each of the two blocks. 2. The set of building blocks of claim 1, wherein each of the at least one core portion of each block is further spaced apart from the corresponding second end and the corresponding first and second opposed faces of the block. 3. The set of building blocks of claim 1, wherein the half interlock of each block has an arcuate shape. 4. The set of building blocks of claim 1, wherein the first and second opposed faces of each block are finished in an aesthetically pleasing manner. 5. The set of building blocks of claim 4, wherein the second end of at least one of the blocks is similar in appearance to the first and second opposed faces of the block. 6. The set of building blocks of claim 1, wherein each block further comprises another half interlock protruding from the first substantially flat load bearing surface at the second end of each block. 7. The set of building blocks of claim 1, wherein at least one of the blocks further comprises a splitter wedge. 8. The set of building blocks of claim 2, wherein at least one of the blocks further comprises a splitter wedge proximate to one of the at least one core portion of the block. 9. The set of building blocks of claim 1, wherein at least one of the blocks further comprises a full interlock protruding from the first substantially flat load bearing surface of the block, the full interlock being spaced apart from the first and second ends and the first and second opposed faces of the block. 10. The set of building blocks of claim 9, wherein the full interlock of the at least one block has an arcuate shape. 11. The set of building blocks of claim 9, wherein the at least one core portion of the at least one block comprises a first core portion and a second core portion, the first core portion being located between the first end of the block and the full interlock of the block, and the second core portion being located between the second end of the block and the full interlock of the block. 12. The set of building blocks of claim 9, wherein the at least one block further comprises another half interlock protruding from the first substantially flat load bearing surface at the second end of the block. 13. The set of building blocks of claim 1, wherein each of the first and second ends includes a flat surface that lies in a plane that is oblique to each of the first and second opposed faces. 14. A set of building blocks useful in forming at least a portion of a wall, each block comprising: first and second opposed faces; first and second opposed ends extending from the first face to the second face; and first and second substantially flat and opposing load bearing surfaces extending, parallel to one another, from the first end to the second end and from the first face to the second face a first inner core extending into the block, from the first substantially flat load bearing surface to the second substantially flat load bearing surface, and being spaced apart from the first and second ends and from the first and second opposed faces; a pair of end core portions, one formed in the first end and the other in the second end, the end core portions extending between the first substantially flat load bearing surface and the second substantially flat load bearing surface; and a first protruding interlock extending out of the block, from the first substantially flat load bearing surface, the first protruding interlock forming at least a portion of a periphery of one of: the first inner core and one of the pair of end core portions to define an interlock core, and a periphery of the other being approximately flush with the first substantially flat load bearing surface and without a protruding interlock; wherein the first protruding interlock of one of the blocks is configured to mate with either the first inner core or one of the end core portions of another of the blocks, but not with the interlock core of another of the blocks, for a given arrangement of the two blocks, in which one of the substantially flat load bearing surfaces of a first of the two blocks faces one of the substantially flat load bearing surfaces of a second of the two blocks, the first protruding interlock not fitting within the interlock core of the another of the blocks; and when the first protruding interlock of the first of the two blocks mates with one of: the first inner core of the second of the two blocks and the end core portion of the second of the two blocks, the facing substantially flat load bearing surfaces of the two blocks come into direct contact with one another. 15. The set of building blocks of claim 14, wherein at least one of the blocks further comprises a second inner core extending into the block, from the first substantially flat load bearing surface to the second substantially flat load bearing surface, and being spaced apart from the first inner core, from the first and second ends and from the first and second opposed faces. 16.
