Jonathan is buried in a tomb in Modein (1 Macc 13:25-13:30)

“Simon sent and took the bones of his brother Jonathan. They buried him in Modein, the city of his ancestors. All Israel bewailed him with great lamentation. They mourned for him many days. Simon built a monument over the tomb of his father and his brothers. He made it high so that it might be seen, with polished stone at the front and back. He also erected seven pyramids, opposite one another, for his father and mother and four brothers. For the pyramids he devised an elaborate setting, erecting about them great columns. On the columns he put suits of armor for a permanent memorial. Beside the suits of armor, he carved ships, so that they could be seen by all who sail the sea. This is the tomb which he built in Modein. It remains to this day.”

Simon had the bones of his brother brought back to Modein, where the rest of his family was buried. There was great bewailing, mourning, and lamentations over the death of Jonathan. However, Simon built a special monument to his family. He built 7 pyramids for his parents and his siblings. He also built great columns with suits of armor and carved ships. This giant tomb could not be seen from the sea, but it was meant as a memorial for those who do sail the seas. However, they did have a sea port in Joppa. This great monument certainly existed at the time of the biblical author of this book.
